Explanation:

In c or c++ or java programming language, there is a different type of data type which is used to hold the data. There are 2 types of data which are used in the above questions are--

1. int data type=> It is used to store the data of integer type. It is of two types long int and int.
2. char data type=> It is used to sore the data of character type.

• In option 1, The long int variable takes the data of the int type variable. which can be done because both are the integer data type.
• In option 2, The int variable takes the data of the long int type variable. which can also be done because both are the integer data type.

Hence option 1 and 2 are the correct option because it compiles successfully while the other is not because--

• In option 3, The char variable takes the data of the int type variable. which can not be done because both are the different data type and it gives a compilation error.
• In option 4, The int variable takes the data of the char type variable. which can not be done because both are the different data type and it gives a compilation error
