Fill in the blank with the most appropriate option.
Please ring me up as soon as he ______

Correct option is C

The correct option to fill in the blank is (c) comes.
Explanation: When referring to future time after “as soon as,” we use the Simple Present Tense, not the future tense. This is a standard rule in conditional or time clauses.
Example: I will call you as soon as she arrives.
Why other options are incorrect:
· (a) has come: Present Perfect – not used in time clauses for future reference.
· (b) came: Simple Past – incorrect for future time context.
· (d) will come: Future tense – incorrect after “as soon as.”
�� Information Booster: After time conjunctions like when, before, after, until, as soon as, use Simple Present to express a future event.
