Solution

The correct option is C 4 byte

A 32 bit microprocessor has the word length equal to 4 byte

One convention is that a byte is an 8-bit word, and a word is two bytes, and a double word (dword) is four bytes. I seem to recall the use of the term quad-word, or qword, being 8 bytes in length used in some assemblers.

A 32 bit processor processes data in 32 bit chunks at a time. If the chunks represent integers, it means it can process numbers from 0 to 4,294,967,296 unsigned or half of that if a bit is used for sign (positive or negative).

microprocessor: indicates the width of the registers. A 32-bit microprocessor can process data and memory addresses that are represented by 32 bits. bus : indicates the number of wires in the bus.
