The correct answer is C.
A byte is a unit of digital information that consists of eight bits. A bit is the smallest unit of information in computing and is represented by a 0 or a 1. The number 1011 1001 0110 1110 is a binary number, which means that it is represented by a series of 1s and 0s. This number can be broken down into four bytes, each of which consists of eight bits. The first byte is 1011 1001, the second byte is 0110 1110, the third byte is 1011 1001, and the fourth byte is 0110 1110.
Option A is incorrect because there are four bytes in the number 1011 1001 0110 1110, not one.
Option B is incorrect because there are four bytes in the number 1011 1001 0110 1110, not two.
Option D is incorrect because there are eight bits in each byte, not eight bytes in the number 1011 1001 0110 1110.
Option E is incorrect because there are four bytes in the number 1011 1001 0110 1110, not none.
