Topic: verb (ক্রিয়া),

Best Answer Explained in Below-:

In the sentence "The Examiners made us ............ our identification in order to be admitted to the exam center," the correct option to fill in the blank is "show" (option B). This is because the verb "made" is a causative verb, which influences how the subsequent verb is structured.

When using a causative verb like "made," the structure that follows typically involves the base form of the verb. In this context, "made us" requires the base form of the verb "show." Therefore, rather than saying "made us showing" (which is incorrect), "made us showed" (which is also incorrect because "showed" is the past tense), or "made us to show" (which misuses the infinitive structure), the appropriate form is simply "made us show."

This grammatical requirement indicates that the Examiners requested or compelled us to present our identification. Thus, the correct sentence reads: "The Examiners made us show our identification in order to be admitted to the exam center." This structure effectively conveys the intended meaning without grammatical errors.
