Answer:
D. 1K
Explanation:
The address space 0x0000-0x3FF is of 1KB(One Kilo Byte) since 0x3ff is equal to 1023. therefore 1023=1 KB.
bitwise 0x3ff zeros out the top bits of the number such that the result is always between 0 and 1023. It is essentially the same thing as modulo( num,1024) for positive values of num.
Hence the answer is D 1K
