Question

Fill in the blank :- You must check the petrol _______ regular intervals.

• A. in
• B. at
• C. with
• D. within

Answer 1

The Correct Option is C

To solve the given question, we need to find the appropriate preposition that fits in the blank: "You must check the petrol _______ regular intervals." Let's evaluate each option:

1. Option: in
   The preposition "in" generally indicates a position within something or during a period. It doesn't convey the correct meaning in this context of checking something at intervals.
2. Option: at
   "At" is used to point out specific points in time or locations. While a possibility, it doesn’t fit as naturally as the correct answer.
3. Option: with
   The preposition "with" is appropriate here as it is often used when discussing quantity, manner, or accompanying actions. In phrases like "with regular intervals," it means doing something in a scheduled or mannered way.
4. Option: within
   "Within" implies something happening inside a boundary or limit, typically of time or space. This does not fit the context as the intervals are not confining boundaries but rather scheduled points in time.

Thus, the most fitting preposition here is "with", making the correct answer: "You must check the petrol with regular intervals."

In conclusion, the correct completion of the sentence is using the preposition "with" because it best implies a measured, consistent pattern of action with respect to time intervals.
