Correct option is D
The correct option to fill in the blank is (d) made.

Example: She made a bold decision to resign from her job.
Why other options are incorrect:
· (a) have – Incorrect auxiliary verb for singular subject “she”.
· (b) do – Incorrect verb for the phrase “do a decision” (collocation error).
· (c) make – Present tense; sentence is in past.
