the first is correct.
The formual for calculating gravationl force between two objects is g=G(m1*m2)/r^2
Now, did the mass change. No, the mass did not change, just the diameter of the sun.
Did the distance from center to center change? Nope, that is also the same.
Therefore the gravational foce would not change.

Surely, the distance of the earth and sun is is given and constant, if the space occupied by the sun or the sun becomes a black hole, the distance between the earth and the sun would become vertical horizon, why? because all the planets including the earth will be dragged to the center of the vortex of the black hole caused by the momentum from the beginning, which is still in effect that causes all the planets to revolve around the sun and what prevents them from dragging to the center is the thermo nuclear heat created from fission and fussion of molecules in the sun.
The propulsive force created from heating is indeed pushing all the planets from being dragged to the center.

The earth's orbit might proceed to be precisely the comparable (a black hollow would not pull extra suitable than a action picture star with the comparable mass) yet devoid of easy and warmth ability our planet might look extremely diverse. it would be a depressing and freezing rock with probable no existence of any style on it.

The gravitational field outside a black hole is identical to the field produced by any other spherically symmetric object of the same mass.
this is what you need to know to answer it yourself.
