ANSWER

The underlined word, along with the options, are prepositions. They express a relation between a noun and its surrounding words/elements.

Options B and D: 'For' and 'since' both refer to time, but they are used in different ways.

'For' mentions a quantity of time (two days, three weeks, etc.).

'Since' mentions a specific point in time till the present. For example, 'We've been living here since 1984.'

In the given sentence, the quantity of time is mentioned: "the last two hours", hence 'for' is the correct word used.

So, no change is required and option D is correct, B is incorrect.

Option A: 'From' indicates a starting point in space or time. For example, 'from this corner to that corner', or 'half an hour from now'. It isn't relevant here, hence A is incorrect.

Option C: 'By' expresses a deadline, for example, 'by 10 a.m.', 'by noon'. The given sentence does not indicate a deadline.
