The correct answer is B: That lizard's eyes were small and shiny. All other options are wrong because the noun was turned into its plural form "lizards," which can't be used with the singular adjective "that." In addition, option C lacks a possessive form and option D includes an "s" after the apostrophe, which should not be used with nouns ending in s.
The correct answer is the option B. Possessive nouns demonstrate possession, ownership, origin or purpose. The singular possessive case is a singular noun or pronoun that indicates something belonging to that person or object. For a singular noun that does not end with an S, in this case, we have a lizard, add an apostrophe 's to the end of the noun to form the possessive. In that case, the singular possessive will be lizard's. It's not the option A, because it's not a noun that end with an S. This rule applies for singular nouns that end with an S, for example, you just add an apostrophe s ('s) to the end of the noun: The meeting is in the boss's office. The option D is not correct because that rule applies for a plural noun that ends with S, for example, The doctors' offices are in a separate building. And the final option C, it's not grammatically correct as for possessives you need to add an apostrophe.
