Answer 3

Pointers require Indirect Addressing modes as the instruction contains address of the memory location from where where the operand will be accessed further.

Arrays requre indexed Addressing mode.

Hence it appears that option (D) is correct.

Answer 4

Pointers -> Indirect Addressing Mode

Array -> Indexed  Addresiing Mode
