Answer 1

The correct option is D $\begin{array}{ccccc}\text{i}& \text{ii}& \text{ii}& \text{iv}& \text{v}\\ \text{c}& \text{d}& \text{a}& \text{e}& \text{b}\end{array}$

$Aspergillusniger$- Citric acid :
$Aspergillusniger$ is a fungus used for the production of citric acid by fermentation. Citric acid is used for flavouring and preserving the packed foods.


$Clostridiumbutylicum$- Butyric acid :
$Clostridiumbutylicum$ is a bacterial species used to produce butyric acid commercially, by fermentation. Butyric acid is used in manufacture of certain chemicals, food and pharmaceutical industries.

$Saccharomycescerevisiae$- Ethanol :
$Saccharomycescerevisiae$, a yeast, produces ethanol by anaerobic fermentation of substrates like molasses, fruit juices, malted grains and vegetable starches.
This ethanol is used for preparing alcoholic beverages like wine, whisky etc.


$Trichodermapolysporum$- Cyclosporine-A :
$Trichodermapolysporum$ is a fungus that is employed to produce Cyclosporin-A that has immunosuppressive properties. Therefore, it is used to prevent tissue rejection during transplantation.

$Monascuspurpureus$- Statins :
Statins are blood cholesterol lowering agents produced by the yeast, $Monascuspurpureus.$

Final answer :
(C) $\begin{array}{ccccc}\text{i}& \text{ii}& \text{ii}& \text{iv}& \text{v}\\ \text{c}& \text{d}& \text{a}& \text{e}& \text{b}\end{array}$
