(Bacteria is) the most common form of life
(1) Bacteria are
(2) Bacterium are
(3) Bacteria was
(4) No Improvement
Option 1: (1)
Option 2: (2)
Option 3: (3)
Option 4: (4)
Correct Answer: (1)
Solution : The correct choice is the first option.
Explanation:
"Bacteria are" is the correct form because "bacteria" is a plural noun, and the verb should agree in number, so it should be "are" whereas "bacterium are" is incorrect because "bacterium" is a singular form and cannot agree with the plural verb.
So, the correct sentence would be: " Bacteria are the most common form of life."
