Solution

The correct option is C 15 bits

If there are 32 segments, each of size 1k byte, then the logical address should have 15 bits.

To specify a particular segment, 5 bits are required. To select a particular byte after selecting a page, 10 more bits are required. Hence 15 bits are required.

To specify a particular segment, 5 bits are required (since 2^5 = 32). Having selected a page, to select a particular byte one needs 10 bits (since 2^10= 1K byte). So, totally 5 + 10 =15 bits are needed.
