A)Pointers need Indirect addressing mode.

B)Array requires indexed addressing mode.

C)Records requires indirect addressing(incase pointers are used) or indexed(contigous allocation).

Therefore correct  option is D.

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.
