<u>Answer:</u> The correct answer is Option d.
<u>Explanation:</u>
To calculate the molarity of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is KOH
We are given:
Putting values in above equation, we get:
Hence, the correct answer is Option d.
