Answer: a. The idea in independent clauses are not coordinate
Step-by-step explanation: Option b is incorrect because the coordinating conjunction (the second and) takes the role of the semicolon in this sentence, i.e., you can have either, but not both. "Talented and respected" is a valid parallel (participial adjective + participial adjective), so option c is discarded, while option d is false because there are no conjunctive adverbs in the sentence. The real problem is the awkward coordination between "is talented and respected" and "was born in Panama"; those two elements are not related enough to coordinate them as such.
