Replace the correct Preposition in the sentence given below:-

Ravi has been studying in this school for 2020.

Since

The correct answer is Option (2) → Since

Here's why:

• When refers to a specific point in time, not a duration.
• After suggests the start of studying happened after 2020.
• Before suggests the studying ended before 2020.
• Since indicates a starting point in the past and continues to the present (which aligns with Ravi's ongoing studies). "In" is sometimes used for locations or general contexts, but "since" is more precise for denoting the starting point of an action or state that continues up to the present moment.

Therefore, "Ravi has been studying in this school since 2020" clarifies that he began studying in 2020 and likely continues to do so presently.
