Given below are two statements:
Statement-I: In a linear block code, NAND operation of any two valid codewords creates another valid codeword.
Statement-II: To guarantee correction up to t errors in all cases, the minimum Hamming distance in a block code must be $d_{min}=2t+1$. 
In the light of the above statements, choose the correct answer from the options given below.

Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): The ENABLE input of an $m: 2^m$ decoder can be used to increase its size.
Reason (R) :  The ENABLE input in an $m: 2^m$ decoder can be used as the $(m+1)^{th}$ input to result in a$ (m+1): 2^{m+1} $ decoder. 
In the light of the above statements, choose the correct answer from the options given below.
