Question

Match List-I with List-II

List-I (Instructions)	List-II (Addressing Mode)
(A) LDA 2100 H	(I) Immediate
(B) RAL	(II) Register
(C) ADD C	(III) Direct
(D) ANI 08 H	(IV) Implied

• A. A) = (I), (B) = (II), (C) = (III), (D) = (IV)
• B. . (A) = (III), (B) = (IV), (C) = (I), (D) = (II)
• C. (A) = (I), (B) = (II), (C) = (IV), (D) = (III)
• D. (A) = (III), (B) = (IV), (C) = (II), (D) = (I)

Hint:

For understanding addressing modes, remember: - Immediate addressing involves direct value manipulation (e.g., LDA 2100 H). - Register addressing involves registers for operations (e.g., RAL). - Direct addressing uses memory locations directly (e.g., ADD C). - Implied addressing involves no operands (e.g., ANI 08 H).

Answer 1

The Correct Option is A

Step 1: Understand the instructions and addressing modes.

The instruction LDA 2100 H (load) utilizes immediate addressing.
RAL (Rotate accumulator left) employs register addressing.
ADD C (Add contents of register C to accumulator) uses direct addressing.
ANI 08 H (AND immediate with accumulator) employs implied addressing.

Final Answer: \[\boxed{1. \text{(A) = (I), (B) = (II), (C) = (III), (D) = (IV)}}\]
