A

B
Sulphur rock
C
Cattle yard
D
Polluted stream
Detailed Solution
Methanogens are archaebacteria that are strict anaerobes and produce methane.
They live in the gut (rumen) of ruminant animals such as cows and buffaloes, where they help in the digestion of cellulose.
The dung of cattle (gobar) is therefore rich in these bacteria, and they produce methane (biogas) from it.
So they are most abundant in a cattle yard; they are also common in marshy areas and flooded paddy fields.
Hot springs are the habitat of thermoacidophiles, another group of archaebacteria.
Hence methanogens are most abundant in a cattle yard.
