A 32 bit microprocessor has the word length equal to

The correct answer is C. 4 bytes.

A 32-bit microprocessor has a word length of 4 bytes. This means that it can store 4 bits of data at a time. The word length is important because it determines the size of the registers and the memory addresses that the microprocessor can use.

A 2-byte microprocessor would have a word length of 2 bytes, and an 8-byte microprocessor would have a word length of 8 bytes.

None of the above is not the correct answer because it does not specify a specific word length.
