Explanation:

The correct future tense form of the verb "meet" in the given sentence is option 'B' - "will meet".

Explanation in detail:

To determine the correct future tense form of a verb, we need to consider the subject of the sentence and the rules of conjugation for future tense in English.

In this sentence, the subject is "we", which is a plural pronoun. When using the future tense with plural subjects, we use "will" or "shall" followed by the base form of the verb.

Here are the conjugation rules for the future tense:

- For singular subjects (I, you, he/she/it), we use "will" followed by the base form of the verb. Example: I will meet.
- For plural subjects (we, you, they), we use "will" or "shall" followed by the base form of the verb. Example: We will meet.

In the given sentence, the subject "we" is a plural pronoun. Therefore, we need to use "will" followed by the base form of the verb "meet". The correct future tense form of the verb "meet" is "will meet".

Let's analyze the options given:

a) "will meeting" - This is incorrect because it does not follow the conjugation rules for future tense. The verb "meet" should be in its base form after "will".

b) "will meet" - This is the correct answer. It follows the conjugation rules for future tense with plural subjects.

c) "shall have met" - This is incorrect because it uses the perfect tense ("have met") instead of the simple future tense.

d) "shall have been meeting" - This is incorrect because it uses the future perfect continuous tense ("have been meeting") instead of the simple future tense.

Therefore, the correct future tense form of the verb "meet" in the given sentence is option 'B' - "will meet".
