A) Both a and b follows B) Only c follows
C) Only a follows D) Both b and c follows
 
Answer & Explanation Answer: A) Both a and b follows

Explanation:

The police ought to find out the lackenings in existing security arrangements and make up for these inadequacies to strengthen security and thus prevent criminal activities in the forthcoming festival. So, both a and b follow. Arresting the known criminals does not ensure safety, for a novice can also indulge in crime. So, c does not follow.
