• A. Sufficient term
• B. Necessary term
• C. Contingent term
• D. Equivalent term

Answer: (A)

In a simple If-Then statement, the part after "if" (the trigger) is a sufficient condition for the part after "then." That means if the trigger occurs, the outcome must follow. For example, if P happens, then Q happens; P being true guarantees Q. But Q happening does not necessarily mean P happened—there could be other ways to get Q as well. So the trigger is a sufficient term for the conclusion. The other terms don’t fit as well here: a necessary term would be something that must be true for the conclusion to occur, which describes the inverse relationship of the consequent to the antecedent rather than what the antecedent guarantees. An equivalent term would require a biconditional relationship (P if and only if Q), which is not assumed by a simple If-Then statement.
