Hint:

To solve this quickly, associate Trichoderma as a well-known biocontrol fungus (A - II) and Deinococcus with radiation tolerance (C - I), which leads directly to option (B).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Different microorganisms possess distinct physiological, metabolic, and ecological traits that allow them to be classified into specific biological groups and used in various biotechnology applications.

Step 2: Detailed Explanation:
Let us match each microorganism with its corresponding trait:
(A) Trichoderma viride is a soil-dwelling fungus widely used as a biological control agent (biocontrol fungus) (II) to suppress plant diseases caused by soil-borne fungal pathogens.
(B) Methanobacterium is a genus of anaerobic, methane-producing prokaryotes classified within the domain Archaea as methanogenic archaea (III).
(C) Deinococcus (specifically Deinococcus radiodurans) is an extremophile bacterium known for its capacity to survive high doses of ionizing radiation, making it a radiation-tolerant bacterium (I).
(D) Frankia is a genus of nitrogen-fixing, filamentous actinobacteria that forms symbiotic nodules on the roots of non-leguminous actinorhizal plants, making it a symbiotic actinobacterium (IV).
This matching yields the combination: (A) - (II), (B) - (III), (C) - (I), (D) - (IV).

Step 3: Final Answer:
The matching sequence corresponds to option (B).
