Answer - A.
The Terminal count of a modulus 11 binary counter is 1010.
The detailed solution to the question, the terminal count of a modulus 11 binary counter, is provided here.
The binary Modulus-11 counter needs 4 FFs. There are 11 possible states for it. Terminal count denotes the capability of the binary Modulus-11 counter to count. Eleven states correspond from 0 to 10.
The highest value it can count is 10 (1010 in binary), which is the terminal count.
Hence, Option (A) is the correct answer.
