B. it is unweighted code

C. it has odd parity

D. All of the above

Answer: Option B

Solution(By Examveda Team)

A two-out-of-five code is a constant-weight code that provides exactly ten possible combinations of two bits, and is thus used for representing the decimal digits using five bits. Each bit is assigned a weight, such that the set bits sum to the desired value, with an exception for zero.
