Question

Fill in the blank with a suitable preposition.
His birthday is ____________ August 20.
A. in
B. on
C. at
D. from

Answer 1

Hint:For this question try to remember all the rules of options given below and try to make prepositional phrases with them and see which one is accurate and correct in context with the given question and makes sense.

Complete answer:
Option A would be considered incorrect because it is not a suitable answer for the given question. Because “in” is generally used to show something as inside an area or moving from a point outside to a point inside. The sentence with this preposition will be “His birthday is in August 20.” which is incorrect.
Option B is the only correct option here out of all as it perfectly fits as an answer to the question. “On” is generally used to show a position. Generally, it indicates something is on top of something else. The sentence in this case will be “His birthday is on August 20.” And it shows a date and is correct.
Option C is also incorrect for the same reason as option A as it indicates a specific location. The sentence in this case will be “His birthday is at August 20.” And hence this option is incorrect.
Option D on the other hand is also incorrect as it is not a suitable answer for the given question. “From” is used to show the starting point either in space or time. The sentence in this case will be “His birthday is from August 20. which is not making prepositional phrase and hence is incorrect.

Hence the correct answer is option ‘B’.

Note:Each preposition has many uses of them and we have to check every rule of them which is correct according to the question and then choose the right option. “On” is also used at many places but with this question it determines the date which is correct for this question.
