To determine which answer choice is a compound sentence, we need to review what a compound sentence is. A compound sentence is formed by combining two independent clauses (complete sentences) using a coordinating conjunction (such as "and," "but," or "or") or a semicolon.

Looking at the answer choices:

A) "Gardening has many therapeutic benefits." This is a simple sentence, not a compound sentence.

B) "In reality, exercising can be something as simple as planting seeds or pulling out weeds." This sentence contains only one independent clause, so it is also not a compound sentence.

C) "This magnificent project is funded by a grant from Green Planet Organics as part of their Gardens Grow Great Communities program." This sentence is also a simple sentence, as it contains only one independent clause.

D) "I’m Mayor Kenndrick, and I’m thrilled to announce the launch of Wessex County’s first community garden here at South Falls High School." This sentence contains two independent clauses ("I’m Mayor Kenndrick" and "I’m thrilled to announce the launch of Wessex County’s first community garden here at South Falls High School") connected by the coordinating conjunction "and." Therefore, answer choice D is a compound sentence.

So, the compound sentence is D) "I’m Mayor Kenndrick, and I’m thrilled to announce the launch of Wessex County’s first community garden here at South Falls High School."
