C. would have
D. have had

Answer 1

Hint: Conditional sentences are sentences that express one thing contingent on something else, e.g. "If it rains, the picnic will be cancelled". They are so called because the impact of the main clause of the sentence is conditional on the dependent clause.

Complete answer:
The word "would" in the sentence implies that the tense of the sentence is a simple past tense. Thus, in the simple past tense, the answer must be a verb.
Option A is reliable. In the plain past tense, 'had' is. It has, therefore, the tense necessary and is the correct answer.
Choice B is misleading. A grammatically incorrect word is 'would had'. According to the rules of use, the principal verb should not be in the past tense if the auxiliary of the verb is in the past tense.
Choice C is unreliable. In the past tense,' would have' is a modal, but in the present tense, it is used to convey an occurrence. Since the incident in the sentence occurred in the past, the answer can not be C.
Choice D is unreliable. In the present perfect tense, and not in the simple past tense, 'have had' is. Using it would then render the tense of the sentence inconsistent.
Additional Information:
For learners of English as a second language, conditional sentences are often confusing.
There are three types of conditional sentences.
I condition possible to fulfil
II condition in theory possible to fulfill
III condition not possible to fulfill (too late)
Form-
I Simple Present will-future or (Modal + infinitive)
II Simple Past would + infinitive *
III Past Perfect would + have + past participle *

Hence the correct answer is option ‘A’

Note:To improve your knowledge about conditional sentences you should brush up the rules of grammar specially related to the use of verbs.
