    Answer : Option A

    Explanation :

    Option A is valid declaration of float.

    Option B is incorrect because any literal number with a decimal point u declare the computer will implicitly cast to double unless you include "F or f"

    Option C is incorrect because it is a String.

    Option D is incorrect because "d" tells the computer it is a double so therefore you are trying to put a double value into a float variable i.e there might be a loss of precision.
