Which of the following is NOT correctly matched?
- ADesalination, Sea water
- BReverse osmosis, Potable water
- CDenaturation, Proteins
- DPasteurisation, Tea
Show answer and explanation
Correct answer: (d) Pasteurisation, Tea
Explanation
Pasteurisation is the brief high-temperature heating of milk (HTST), not tea, so this pair is wrongly matched.
Desalination removes salts from sea water, and reverse osmosis forces water through a membrane to yield potable water.
Denaturation breaks the weak bonds that maintain the structure of proteins.
