Mike Mc Garry Sir based on the wisdom that you gave me
here.
Clause after If is a Subordinate Clause
Clause after then is an Independent Clause.
In Option A we need a full clause i.e. S-V pair and that is not happening in that option, therefore, Option A is wrong.
Options B & C have a full clause after If, but In option B it doesn't agree in number with the plural subject restorers, thus, C is correct.
P.S. GMAT Prep Question
