Answer: (D)

Should you need more money, do not hesitate to ask me.

'If' is a conjunction which is used to express uncertainty about whether an action (or event or condition) will occur. In the event, the particular action (or event or condition) occurs, then the other event is likely to occur.

Option A: The auxiliary verb, 'had' can be used to replace the word' if' in a conditional sentence in the past tense. The given sentence is in the future tense. Hence, 'had' cannot be usedand this option A is incorrect.

Option B: The word, 'unless' is used to replace 'If... not'. In the given sentence, the word, 'unless' replaces 'If'; All other words in the sentence being the same. Hence, this option is incorrect.

Option C: 'Whether' is a conjunction which is used to express a choice between two alternatives or events. Here, there is no such reference. Hence, this option is incorrect.

Option D: The modal, 'should' is used in a conditional sentence in the present tense with a future meaning. The given sentence is a conditional sentence which refers to a future event. Hence, 'should' can be used. The modal, 'should' is used along with the simple present form of the main verb. In the given sentence, 'need' is the main verb. The clause, 'If you need more money', can be rephrased as 'Should you need more money. Hence, option D is correct.
