Answer is (B).
Cache location (memory block) = block req mod number of cache blocks. Since each block has only one location (associativity is $1$) the last mod $8$ request will be in cache (no need of any replacement policy as mapping is direct).
$3, 5, 2, 8, 0, 63, 9, 16, 20, 17, 25, 18, 30, 24, 2, 63, 5, 82, 17, 24$
Block $0- 8$, $ 0, 16, 24, 24$. At end contains $24.$
1- $9, 17, 25, 17. $
2- $2, 18, 2, 82.$
3- $3$.
4- $20.$
5- $5, 5.$
6- $30.$
7- $63 63.$
So, memory block $18$ is not in cache while $3$, $20$ and $30$ are in cache.
