Best Answer Explained in Below-:

The phrase "The principle will---- the answer scripts" requires a phrasal verb that conveys the meaning of reviewing or examining the scripts in a thorough but not overly detailed manner. Among the options provided:

A) "look at" suggests a superficial glance, lacking the implication of an in-depth review; it denotes simply observing without a connotation of careful evaluation.

B) "look into" generally implies investigating or researching, often used in contexts where a deeper exploration of facts or details is required. This does not align with the context of assessing answer scripts in an academic setting.

C) "look over" is the correct choice here. This phrase means to examine something briefly in order to assess it, which fits well with the idea of reviewing answer scripts. It suggests a balanced approach, allowing the principal to check for completeness or correctness without the expectation of an exhaustive assessment.

D) "look for" implies searching for something specific, which does not match the context of assessing or reviewing the answer scripts.

Therefore, "look over" is the most appropriate choice, indicating a focused review process that the principal would undertake.
