First one.
Because Force =massx accleration
and also
Weight that is
W = mg
hence both would have sam e dimension
that is:
MVT^-1

2nd one isVelocity =displacement divided by the time interval i.e s/t, thus diamensional formula becomes. [L^1T^-1]Now,Impulse is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector in the same direction.THUS, it have diamensional formula [L^1T^-1]THUS, VELOCITY AND IMPULSE HAVE DIAMENSIONAL FORMULA=[L^1T^-1]

(A) As force=mass × acceleration.Therefore MLT^-2.And weight=mass×acceleration.Therefore the dimension is MLT^-2. Hence (A )is the answer.
