  • Correct answer
    B

  • C

  • D
    No Error

Solution

We do not use the indefinite articles ' $a$ ' or 'an' with uncountable nouns. Thus, 'a liquid' is incorrect. The correct sentence will be 'When a gas is cooled down it turns into liquid from a process called condensation.'.

Hence, the correct answer is option: 'B'.
