Which statement about plurals is accurate?

The accurate choice identifies that both statements regarding plurals are correct.

The term "datum" refers to a singular piece of information, and its correct plural form is "data." Many might mistakenly think "datums" could serve as a plural, but in standard usage, "data" is the accepted plural form. Therefore, the assertion regarding "datums" being an incorrect plural is indeed accurate.

In the case of "analysis," the correct plural form is "analyses." The use of "analysis's" suggests a possessive form rather than a plural, which makes the statement about "analysis's" being an incorrect plural accurate as well. This highlights the importance of distinguishing between pluralization and possessive form in English grammar.

Consequently, identifying both statements as correct reflects an understanding of proper plural forms in English, demonstrating a comprehensive grasp of the distinctions between singular, plural, and possessive grammatical structures.
