Answer 2

The ‘number of ways’ in which the ‘operand information’ is specified in the ‘instruction code’ is 5.

Option: (b)

Explanation:

The several ways of specifying the operands or data for instructions are known as addressing modes. The 8085 addressing modes can be ‘classified’ into 5 types. They are  

    1) Immediate addressing modes

    2) Register addressing modes

    3) Direct addressing modes

    4) Register indirect addressing modes

    5) Implicit addressing mode

The format of typical instruction can be composed of two parts namely op-code, operation code, and an operand. Each and every instruction should have an opcode.
