My mother . . . . . . . . up early in the morning. A. get B. gets C. will be D. shall be

The correct answer is gets.

The verb “get” is used to describe the act of rising from bed. It is a regular verb, so the past tense and past participle are formed by adding -ed. The present tense form is “gets”.

The other options are incorrect because they do not agree with the subject of the sentence, which is “my mother”. The subject is singular, so the verb must also be singular.

• Will be is the future tense form of the verb “to be”. It is used to describe actions that will happen in the future. In this case, it would not be correct to use the future tense because the action is happening in the present.
• Shall be is the formal version of the future tense. It is used to describe actions that are certain to happen. In this case, it would not be correct to use the formal version of the future tense because the action is not certain to happen.

Therefore, the correct answer is gets.
