Choose the most suitable option to replace the highlighted part of the sentence: The baby was sleeping since two hours.
for two hours
The rule:
since is used with a point in time — "since 6 a.m.," "since Monday," "since 2018."
for is used with a duration — "for two hours," "for ten years."
"Two hours" is a duration, so the correct preposition is for: "The baby was sleeping for two hours."
The other options are wrong:
from two hours — incorrect; "from" needs a starting point, not a duration.
by two hours — "by" is used for deadlines, not durations.
since two hour — wrong both in preposition and in number ("hour" should be "hours").
Hence the correct answer is for two hours.
