The most appropriate option to fill in the blank is:

Official

Explanation: In this context, the word "official" suggests that the medicine being administered is recognized and approved by the relevant authorities or medical professionals. It implies that the medicine is legitimate and prescribed within the official protocols of medical practice.

The other options do not fit well in the context:

"Eminent" means distinguished or noteworthy, but it doesn't directly relate to medicine in this context.

"Alternative" suggests a different option, which may not align with the doctor's directive.

Insightful" refers to having a deep understanding or perception, which doesn't make sense in the context of administering medicine.

Unconditional dedication" implies unwavering commitment and loyalty to the company regardless of circumstances. While support, attachment, and love can also be relevant in the context of an employee's relationship with their company, "dedication" specifically captures the idea of steadfast loyalty and commitment. Therefore, option 2 is the best fit for the sentence.

(A) bought - "They bought vegetables last week." The past tense of the verb "buy" is needed in this context to match the timeframe mentioned.

(C) is - "Ram as well as his brothers is coming today." The subject "Ram as well as his brothers" is singular, so the verb should be singular as well.

(C) Every - "Every boy and girl should go to college."

(C) till - "She sat here till 8 O'clock."

(D) for - "She was blamed for the failure."

(C) into - "He lost control of the car and crashed into a wall."
