A) The rate of catalytic hydrogenation is faster in than in and
B) The rate of catalytic hydrogenation is faster in than in .
C) has a cyclopropene ring whose strain on going to less strained cyclopropane ring is reduced on hydrogenation. Similarly, cyclobutene ring in on hydrogenation is reduced to less-strained cyclobutane ring. But cyclopropene ring is more strained than cyclobutene ring, so faster hydrogenation is in than in .
D) There is a little change in the ring strain when the cyclohexene ring is reduced.
