Varun’s mother added plenty of salt to the mango pickle she made. This is to:
A. enhance the colour of the pickle.
B. inhibit the growth of microorganisms.
C. increase the nutritional value.
D. create a hypertonic solution.
(a) A and C
(b) B and C
(c) C and D
(d) B and D
(d) B and D
Explanation: The salt creates a hypertonic medium. Water leaves microbial cells by osmosis, inhibiting their growth and helping preserve the pickle. Salt is not added to increase its nutritional value or enhance its colour.
