Correct the sentence: ‘The committee have decided their course of action.’

The correct sentence is "The committee has decided their course of action." This correction addresses a common grammatical rule concerning subject-verb agreement, particularly with collective nouns. A collective noun, such as 'committee,' 'team,' 'family,' or 'group,' can be treated as either singular or plural depending on the context. When the members of the collective noun are acting together as a single, unified entity, the noun is considered singular, and thus requires a singular verb ('has'). In the original sentence, 'the committee have decided their course of action,' the committee is acting as one unit to make a single decision, indicating a singular action. If the members were acting individually or expressing differing opinions, a plural verb ('have') would be appropriate. However, 'decided their course of action' implies a unified decision, making 'has' the correct choice for singular agreement.
