Question

Which of the following is true about the cache? Line size
Line size >block size

Answer 1

I think that is false!

Answer 2

Cache block is a synonym for cache line.  Depending on the text to be read, it will use a minimum unit of address allocation in the cache.  So, in your example, an L1 cache reads miss in L1 with a 32B line size (i.e.cache block size), the L1 controller will allocate read 32 bytes.
