The correct answer is C. too.
The word “too” is used to express that something is more than enough or more than is necessary. In this case, Chintu is too small to start playing cricket now. This means that he is not yet old enough or strong enough to play the game safely and effectively.
The word “very” is used to express that something is to a great extent or degree. In this case, it would not be correct to say that Chintu is very small to start playing cricket now. This is because there is no specific age or size requirement for playing cricket.
The word “much” is used to express a large amount or quantity. In this case, it would not be correct to say that Chintu is much small to start playing cricket now. This is because there is no specific amount of smallness that is required to play cricket.
The word “more” is used to express a greater amount or quantity than something else. In this case, it would not be correct to say that Chintu is more small to start playing cricket now. This is because there is no specific amount of smallness that is required to play cricket.
