If it's raining tomorrow, we shall have to ______ the match till Sunday.A. put offB. keep onC. carry outD. call off

To fill in the blank in the sentence, we need to choose the word that best fits the context of postponing an event due to rain. Here's an analysis of the options given:

1. A. put off: This means to postpone something to a later time or date. This fits well in the context of the sentence, as it implies that the match will be delayed until Sunday.

2. B. keep on: This means to continue doing something. This option does not make sense in the context of the sentence because if it's raining, you are not continuing the match.

3. C. carry out: This means to perform or execute. It does not fit the context either, as the sentence implies that the match will not be carried out if it's raining.

4. D. call off: This means to cancel something that was planned. While this option is also plausible, it emphasizes cancellation rather than postponement.

Given the context of the statement which indicates a requirement to delay the match, the best choice is:

Final Answer

A. put off
