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:
This is a question of ‘If’ based conditional sentences. So according to the rules, we will use past verbs here.
Due to the concept of past verbs in conditional sentences Option A, Option B, and Option C are incorrect because they are indicting the verbs of the present.
Option E is also incorrect because we treat ‘I’ as a singular number so the use of ‘were’ is incorrect here.
Option D is showing the correct grammatical format for this condition hence Option D is the correct answer.

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 ‘D’

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