Suppose we are working with an error-correcting code that will allow all single-bit errors to be corrected for memory words of length 7. We have already calculated that we need 4 check bits, and the length of all code words will be 11. Code words are created according to the Hamming Algorithm. We now receive the following code word: 1 0 1 0 1 0 1 1 1 1 0. Assume even parity. Received codeword has one bit in error. whre is the error?

a. The error is in bit 11.

b. The error is in bit 5.

c. The error is in bit 7.

d. The error is in bit 9.

e. The error is in bit 3.
