    Answer : Option A

    Explanation :

    Math.random() returns a double value greater than or equal to 0 and less than 1. Its value is stored to an int but as this is a narrowing conversion, a cast is needed to tell the compiler that you are aware that there may be a loss of precision.

    The value after the decimal point is lost when you cast a double to int and you are left with 0.
