Can you help please with full explanation?

2. Let's say we have 256(=28) byte main memory and 16-byte direct-mapped cache. The cache has 4 lines as shown in the table below. Assuming that the CPU wants to read a data from a memory location whose logical address is h'69, answer the following questions below. Note h indicates the following number is a hexadecimal number. The byte in the right most column has the lowest address in a line. (a) Line number ( 0.4 mark) (b) Tag (0.4 mark) (c) Is it a hit or a miss? Why? ( 0.4 mark) (d) Data read in case of a hit (in case of a miss, write N/A) (0.2 mark)
