“If you like ketchup and you also like ice-cream, then you would sure like ketchup ice-cream.” Which fallacy is committed in this argument?

Correct option is D

(d) Fallacy of composition
The fallacy committed in the given argument is the "Fallacy of Composition." This fallacy occurs when it is assumed that what is true for individual parts will also be true for the whole. In this case, liking ketchup and liking ice cream individually does not logically lead to the conclusion that one would like ketchup ice cream. Each preference exists in separate contexts, and combining them does not necessarily yield a favorable outcome. The argument erroneously assumes that the properties of the individual components (ketchup and ice cream) will combine harmoniously when, in reality, this combination is not guaranteed to be desirable.
