The correct answer is
When I arrive, I will call you.

Correct Sentence: Future Conditionals with 'When'

In English grammar, when a subordinate clause starting with 'When' refers to a future event, the verb in that subordinate clause should be in the simple present tense. The main clause, however, uses the simple future tense (will + base verb).

Sentence Analysis

Option (a): When I would arrive, I will call you.

Incorrect. The use of 'would' is inappropriate here. 'Would' is generally used for past habits or hypothetical conditionals, not for simple future conditions introduced by 'When'.

Option (b): When I shall arrive, I will call you.

Incorrect. While 'shall' can indicate future tense, especially for the first person ('I', 'we'), the standard rule for 'When' clauses referring to the future requires the simple present tense, not 'shall'.

Option (c): When I will arrive, I will call you.

Incorrect. This sentence incorrectly uses 'will' in the subordinate 'When' clause. The rule dictates the simple present tense ('arrive') should be used here when discussing a future event.

Option (d): When I arrive, I will call you.

Correct. This sentence correctly follows the grammatical rule. The 'When' clause ('When I arrive') uses the simple present tense to refer to a future action, and the main clause ('I will call you') correctly uses the simple future tense.

Therefore, the correct sentence structure for expressing a future condition with 'When' is demonstrated in option (d).
