Question

Match List I with List II :

List I	List II
(A) Temperature	(III) Kelvin (K)
(B) Mass	(I) Kilogram (kg)
(C) Electric current	(IV) Ampere (A)
(D) Length	(II) Meter (m)

Choose the correct answer from the options given below :

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

Hint:

The 7 SI base units are: Meter (Length), Kilogram (Mass), Second (Time), Ampere (Current), Kelvin (Temp), Mole (Substance), and Candela (Luminosity). Knowing these handles almost all matching unit questions.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This question involves matching physical quantities with their respective SI (International System of Units) units.
Step 2: Detailed Explanation:
1. Temperature (A): The SI unit of temperature is the Kelvin (K). Thus, (A) matches with (III).
2. Mass (B): The SI unit of mass is the Kilogram (kg). Thus, (B) matches with (I).
3. Electric Current (C): The SI unit of electric current is the Ampere (A). Thus, (C) matches with (IV).
4. Length (D): The SI unit of length is the Meter (m). Thus, (D) matches with (II).
Step 3: Final Answer:
The matching combination is (A)-(III), (B)-(I), (C)-(IV), (D)-(II). This corresponds to option (4).
