Correct Answer:
B. If he were available, he would attend.
The subjunctive mood is used to express wishes, suggestions, commands, or conditions that are contrary to fact or highly improbable. A key indicator in hypothetical "if" clauses is the use of "were" instead of "was" for all subjects, even singular ones.
- The correct answer, If he were available, he would attend, accurately uses the subjunctive mood. "If he were available" expresses a hypothetical condition contrary to fact (implying he is *not* available). The use of "were" with the singular subject "he" is characteristic of the subjunctive.
- "If he was available, he would attend" uses the indicative mood, which is generally considered incorrect for such contrary-to-fact conditions in formal English.
- "He is available to attend" and "He attends meetings regularly" are both in the indicative mood, stating facts or habitual actions.
The subjunctive mood is essential for expressing non-factual or desired situations.
