She said that she _____ (visit) London next month. Here the right form verb will be-

The right form of the verb to complete the sentence "She said that she _____ (visit) London next month" is:

D. would visit

Explanation:

• "visited" is the simple past tense form. It's not suitable here because the sentence is about a future event relative to the time of speaking.

• "will visit" is the simple future tense form. However, when reported speech is used (as indicated by "She said that..."), the tense usually shifts back. So, if the original speech was "I will visit London next month," in reported speech it becomes "She said that she would visit London next month."

• "had visited" is the past perfect tense form, which indicates an action completed before another past action or time. It's not appropriate for a future event.

• "would visit" is the correct form. It's the past form of "will" and is used in reported speech to talk about future plans or intentions that were stated in the past.
