Column-I	Column-II
$A$. Citric acid	$p$. Methanobacterium
$B$. Cyclosporin A	$q$. Monascus purpureus
$C$. Statin	$r$. Aspergillus niger
$D$. Gobar gas	$s$. Trichoderma polysporum
	$t$. Clostridium butylicum

• A. A- r, B- s, C- Q, D- p
• B. A- t, B- q, C- s, D- r
• C. A- q, B- s, C- t, D- r
• D. A- r, B- s, C- q, D- t

Answer 1

The correct option is A A- r, B- s, C- Q, D- p

Aspergillus niger is used in the production of citric acid and it is one of the most commercially utilized organisms. Cyclosporine A, an immunosuppressant drug is produced by the fungi Trichoderma. Cholesterol-lowering statins have been produced by the mould, Monascus purpureus. For the production of gobar gas, by fermentation, Methanobacteirum is used.

Thus, the correct answer is option (A).
