a) Of
b) For
c) In
d) At

Answer 1

Hint: You need to choose (from the given options) the preposition that indicates speed or time regarding something.

Complete answer:
 Before finding the correct answer let us discuss prepositions. So, what do we mean by prepositions?
Well, a preposition is a word used to link nouns, pronouns, or phrases to other words within a sentence. They act to connect the people, objects, time, and locations of a sentence.
In the above sentence, we need a proposition that talks about the specified speed.
Now, let us look into the different prepositions that we have and choose the one that is best suited for the above sentence.
So –
Option (a) – ‘of’, the preposition ‘of’ is used to indicate belonging or possession and not indicative of the speed. Therefore, this is not the correct solution.
Option (b) – ‘for’, the preposition ‘for’ is used to indicate the reason behind doing something. Hence, this too is incorrect.
Option (c) – ‘in’, the preposition ‘in’ is used to indicate one point in time, also a drive-in means a place where you do not need to get down from your car. Hence, this is irrelevant here and therefore is the incorrect solution.
Option (d) – ‘at’, the preposition ‘at’ is used to indicate sped or time regarding something. Therefore, this would be the best-suited preposition to complete the sentence.
Therefore, as per the above-given explanation the correct solution is option (d).
So, the complete sentence becomes – Leo is scared of driving. He drives at a speed of 20 km/hr.

Note:
 A drive-in is a place where one doesn’t have to get down from one’s car. So if you use the preposition ‘in’ to complete the sentence the meaning would become something like the one given above.
