Explanation

This sentence displays a special kind of pronoun-antecedent agreement error. Describing  kingdom Eubacteria as   one of  something means that the entity that the singular  kingdom  is  one of  must be plural.

Think about simpler cases: "This program is one of my favorite  shows ," NOT "This program is one of my favorite  show ."

Kingdom Eubacteria is the only  one of ...the classification  system   (a singular noun) is incorrect.

Additionally, the original construction uses the pronoun who, which is used to refer to a person, to describe the  kingdom Eubacteria .

Choice C  uses a simpler and grammatically correct construction to express the same idea.  Kingdom Eubacteria , a singular noun, agrees with the singular verb  displays .  Alone among  is an idiomatically correct expression.  That comprise the classification system  is an adjective clause immediately following the noun it describes,  the six kingdom s.  The correct answer is C.

Choice B  retains the "singular item out of a singular entity" error. Additionally,  they  is used to refer to a singular pronoun,  kingdom Eubacteria .

Choice D  uses the plural are to describe a singular noun,  kingdom Eubacteria .  In displaying  is an awkward and unclear prepositional phrase.

Choice E  retains the singular item out of a singular entity error. Additionally,  only of  is an idiomatically incorrect, unclear, and awkward way of expressing one item out of several items; this expression would mean a number of things:  the shirt only of (made of) wool.

Cadbury · Answer

The basic difficulty arises in identifying option C as the correct answer. Option C appears to be a run-on sentence because a verb is missing after kingdom Eubateria. Students expect a verb there :- Kingdom Eubateria (is) alone among.... However, the phrase that follows Kingdom Eubacteria   is a modifier, modifying Kingdom Eubacteria. The main verb in this clause is "displays" and agrees with singular Kingdom Eubacteria. This construction is grammatically superior than the other options.

**Chop down the sentence to eliminate some of the clutter**

Able to synthesize chemical energy, kingdom Eubacteria is  the only one of the six-kingdom classification system who displays  the full range of metabolic diversity.

(A) is the only one of the six-kingdom classification system  who  displays --> who should not modify system, it should modify bacteria. ELIMINATE
(B) is alone out of the six-kingdom classification system since they  display  --> eliminate...Eubacteria is established as singular (because of "it" in the original sentence); display in this sentence implies bacteria is plural, thus ELIMINATE
(C) alone among the six kingdoms that comprise the classification system displays --> Correct by POE
(D) are the only  ones  out of the six kingdoms that comprise the classification system in displaying --> ones implies 
(E) only of the six-kingdom classification system displays --> incomplete clause. ELIMINATE
