- A Only (i) is correct
- B Only (ii) correct
- C Both are correct
- D Both are incorrect
Answer & Solution
Correct Answer
(C) Both are correct
Step-by-step Solution
Detailed explanation
The viscosity decreases with increase in temperature. Due to this reason, the hot water moves faster than cold water. Since in summer temperature is high, so more viscous oils are used in motorcars.
