7. 'Will you be free tomorrow?' Colin asked Richard. A Richard asked would Colin be free the next day. B Colin asked Richard if he would be free the following day. C Colin asked if Richard will be free tomorrow.

The correct answer is B. Here's why: * Original Question: 'Will you be free tomorrow?' Colin asked Richard. * Indirect Speech: When converting a direct question into indirect speech, we need to make the following changes: * Reporting Verb: 'asked' is appropriate. * Conjunction: Since the question is a yes/no question, we use 'if' or 'whether'. * Pronoun Shift: 'you' refers to Richard, so it becomes 'he'. * Tense Shift: 'will be' becomes 'would be' (future simple to conditional). * Time Expression: 'tomorrow' becomes 'the following day'. Therefore, the correct indirect speech is: Colin asked Richard if he would be free the following day. Correct Answer: B
