What is the genitive singular form of 'illud pulchrum nōmen'?

The genitive singular form of "illud pulchrum nōmen" involves determining the genitive case for both the demonstrative pronoun "illud" and the noun "nōmen."

In Latin, "nōmen" (name) is a neuter noun of the third declension, and its genitive singular is "nōminis." The phrase "illud pulchrum" indicates a specific demonstrative pronoun modifying "nōmen."

The genitive singular form of "illud" is "illius," which indicates possession or association. When combined with "pulchri," which is the genitive singular form of "pulcher" (meaning beautiful) in agreement with its neuter noun, the complete expression becomes "illius pulchrī nōminis."

This formulation correctly captures the relationship of possession in this context, making option B the right answer as it correctly combines the elements needed for expressing the genitive singular form of "illud pulchrum nōmen."
