Arrange the sentence parts:
(A) to the office
(B) reached
(C) Mr. Sharma
(D) at 9 am

Correct option is C

Option (c) is the correct order of the given sentences (CBAD).
Why this order is correct:
· Subject first: (C) Mr. Sharma establishes the subject.
· Main verb next: (B) reached completes the core predicate with the subject.
· Place adjunct then time adjunct: (A) to the office (place) logically precedes (D) at 9 am (time), yielding a clear S–V–Place–Time order.
· The full sentence formed is: “Mr. Sharma reached to the office at 9 am.”
· Note (usage tip): In standard usage, reach usually doesn’t take to before a noun ( “reached the office”). Given the fixed fragments include “to the office,” CBAD is still the best-formed sequence among the options for exam purposes.
