A is your answer. You a doing a halogenation (a type of addition reaction). Anytime you see a double bond reacting with a halogen (X2), you will get the dihalide product (provided that there is no mention of water or alcohol).

CH2=CH2 + Br2 ------------> CH2Br-CH2Br
ethene bromine 1,2 dibromo ethane
Which of the following statements are true ?
a) The product is CH2Br-CH2Br : true
b) This is an elimination reaction : false as it is an addition reaction
c) CH2=CH2 is an alkyne :false as ethene is an alkene, an alkyne has a C-C triple bond
d) The product will contain only double bonds : false as the C-C double bond opens up to accomodate the 2 Br atoms coming in (adding), so that the product has only all single bonds

Don't listen to everything that winged phallus guy has to say!
c) is NOT true. CH2=CH2 is an alkEne, not alkYne
