Directions: The item consists of two statements, one labeled as the ‘Assertion (A)’ and the other as ‘Reason (R)’.You are to examine these two statements carefully and select the answers to the item using the codes given below:Assertion (A): Source produces two symbols A and B with probability 3/4 and 1/4 respectively. For error-free transmission, this source should be coded using Shannon-Fano code.Reason (R): For better transmission efficiency, source and channel must be matched.

• A. Both A and R individually true and R is the correct explanation of A
• B. Both A and R are individually true but R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true
