The correct option is (c) both operands can be direct/indirect register operands

To elaborate: In data transfer instructions,

1. Program counter is not accessible.

2. Restricted bit-transfer operations are allowed.

3. Both operands can be direct/indirect register operands.

4. BOth operands can be internal direct data memory operands.
