D Correct answer
Explanation

As variable 'i' is of double and 'j' is of float , we cannot assign a data type with lower precedence with data type of higher precedence. Explicit type cast must be done in order to assign a data type with lower precedence with a data type of higher precedence. i.e float j=(float)i; which type casts the double datatype to float data type As the explicit type casting is not done in the given program, hence we get run time exception.
