I have not met him ________ last Wednesday.
Asince
Bfrom
Cfor
Dby
Answer:
A. since
Read Explanation:
Since is used with a specific point of time when an action started or when a situation began.
Last Wednesday is a specific point of time, so since is correct.
The present perfect tense (have not met) commonly goes with since to indicate a period continuing up to the present.
Why the others are incorrect:
since ✅ → Used with a specific point of time.
from ❌ → From last Wednesday would normally need another time reference, such as from last Wednesday onwards.
for ❌ → Used with a period of time, e.g., for two weeks.
b ❌ → Not a suitable preposition.
