Q32

A $4$ kilobyte $\text{(KB)}$ byte-addressable memory is realized using four $1 \mathrm{~KB}$ memory blocks. Two input address lines $\text{(IA4 and IA3)}$ are connected to the chip select $\text{(CS)}$ port of these memory blocks through a decoder as shown in the figure. The remaining ten input address lines from $\text{IA11-IA0}$ are connected to the address port of these blocks. The chip select $\text{(CS)}$ is active high.

The input memory addresses $\text{(IA11-IA0)},$ in decimal, for the starting locations $\text{(Addr = 0)}$ of each block (indicated as $\text{X1, X2, X3, X4}$ in the figure) are among the options given below. Which one of the following options is $\text{CORRECT}?$
