Explanation

The correct sentence is:

A) The intricate interplay of genetics and epigenetics, along with the influence of environmental factors, shape an individual's health outcomes.

Here's why:

• Subject-Verb Agreement: The plural subject "intricate interplay" requires the plural verb "shape."
• Noun Pluralization: "Genetics" and "epigenetics" are already plural nouns.

The other options have either incorrect pluralization or subject-verb agreement errors.

Explanation

The correct sentence is:

A) Irrespective of the diverse opinions, the committee has convened to discuss the pressing issues.

Here's a breakdown of why this is correct:

• "Irrespective of" is a prepositional phrase that correctly modifies the entire clause.
• "The committee" is a singular subject, so the verb should be singular as well: "has convened."

The other options have either grammatical errors or incorrect usage of the prepositional phrase.

Explanation

The correct sentence is:

A) Regardless of the myriad challenges, the dedicated team is determined to pursue their ambitious goals.

• "Myriad" is already a singular adjective, so adding "s" to it would be incorrect.

Therefore, option A is the grammatically correct choice.

• "Intricate data sets" is the correct form, as "data" is typically treated as plural, and "sets" refers to multiple collections of data.
• "Meticulously analyze" is the correct verb form to match the context of detailed examination.
