the clauses to be seen on each option
(a) hut-will catch fire with lightning
(b) closed car-the tyres are bad conductor of elecricity.

here i took this from howstuffworks.com. check out the rest of the article about lightning. http://science.howstuffworks.com/lightning.htm
Rubber tires keep you safe in a car because they do not conduct electricity.
Nope. In strong electric fields, rubber tires actually become more conductive than insulating. The reason you are safe in a car is because the lightning will travel around the surface of the vehicle and then go to ground. This occurs because the vehicle acts like a Faraday cage. Michael Faraday, a British physicist, discovered that a metal cage would shield objects within the cage when a high potential discharge hit the cage. The metal, being a good conductor, would direct the current around the objects and discharge it safely to the ground. This process of shielding is widely used today to protect the electrostatic sensitive integrated circuits in the electronics world.

The car is 100% safe.
The rubber tyres are irrelevant, as is whether you touch the metal. Inside a conducting box (a car) you are surrounded by an equipotential - it is impossible for a voltage drop to generate across the box, because it is a conductor. If there is no voltage drop you cannot possibly be electrocuted. However many times the lightning strikes.

Lightning does not simply come from the sky and hit the earth. The positive charge from the clouds is met by the negative charge coming up from the earth so the car is best bet. ie lightning strike is two things which meet in the middle and wouldn't have negative charge from the car. Car acts as a Faraday cage so safest bet.

A hut might catch fire but it probably will not, in any case inside a hut is safer than in the open. The best place is in a car with the windows shut.

A car, no doubt. This makes what we call a "Faraday's cage" : a closed conductor surface has internal voltage equal zero no matter external voltage is . It "blinds" the inside from electromagnetic radiation and from lighting. Tires play no rolle at all.

The metal car body all so dissipates the lighting the lighting will most likely go right throw the huts roof and strike you anyways

I would say hide in the top of a really tall tree and hold on tight to your electric blanket
To the answer above you wouldnt get a shock if you touched something metal as the tires stop the current from earthing and without that... No electricity.

1 in 3 million - that's the probability of being struck by lightning. Of the two i'd rather be in a hut (pizza-type) you still can get the fudge out!!

Electricity always finds a short circuit. so the question is relative, since the hut will be a favourable medium for short -circuit

Car, as long as you don't touch the chasis. Rubber flooring and naturally insulating tyres will probably shield you from the worst of it.
