Answer 2

Move contents from DS to BX register

Explanation:

Content of DS and BX register is 2500H and 1000H, respectively.

In microprocessor 8086, we have AX, BX, CX, DX and DS as registers. AX is called the accumulator. Each register is used to store values and perform operations.

Microprocessors use assembly language to perform functions.

MOV instruction is used to move contents from one register to other. The content where it is present is called the source register and where it is moved is called the destination register.

To move contents from DS to BX, use command:

MOV BX, [DS]

Here DS is the source register on the left and BX is the destination register on the right. Content will be moved from the register mentioned in the right to the register mentioned in the left. So content will be moved from DS to BX.
