Solution

✅ Correct Option: 3

Sequential codes run in consecutive order such as CL001, CL002, so (A) matches (II).

Block codes reserve a range of numbers for a class, such as 300 to 399, so (B) matches (IV).

Mnemonic codes use letters that suggest the item, such as DLH for Delhi, so (C) matches (I).

A password acts as a key for access, so (D) matches (III).
