Question

Match the columns

Column-I	Column-II
a) Aspergillus	$1)$ Chemical preservative
b) KMS	$2)$ Acetic acid
c) Vinegar	$3)$ Food poisoning.

A. $a-1,\text{b-2,c-3}$
B. $a-2,\text{b-1,c-3}$
C. $a-3,\text{b-1,c-2}$
D. $a-1,\text{b-3,c-2}$

Answer 1

Hint: Aspergillus is green or yellow-green mold. It mainly grows on corn in the farm or during storage. KMS is the short name used for Potassium metabisulphite. The chemical formula of vinegar is $C{{H}_{3}}COOH$.

Complete step by step solution:
Let us first have some knowledge about the options given in column-I and then we will match the information given in column-II.
- Aspergillus is a green or yellow-green mold that primarily grows on corn in the farm or during storage. It has several types like Aspergillus flavus and Aspergillus niger. A. flavus produces toxins like aspertoxin, gliotoxin, etc. and tends to cause food poisoning. It basically causes infectious disease pneumonia.
- KMS is the short form used for potassium metabisulphite. It is generally used in food industries as a food preservative with a combination of lemon juice. It is also used as a food additive.
- Vinegar can be very well defined as a dilute solution of ethanoic acid in water. Ethanoic acid is also more commonly known as acetic acid having a chemical formula $C{{H}_{3}}COOH$.
 So, the right match will be $a-3,\text{b-1,c-2}$.

Hence, the correct option is C.

Note: Vinegar is basically a diluted solution of acetic acid in water due to this, vinegar is considered to be a weak acid. Potassium metabisulphite is also known as $E224$.
