Final answer:
The set equal to {3,5,7,9,11,13} is represented by option (a), which includes all odd integers between 3 and 14 within the set of integers Z.
Step-by-step explanation:
The question is asking to select the set that is equal to {3,5,7,9,11,13}. Option (a) states x∈Z: x is odd and 3≤x≤14. This definition includes all odd integers between 3 and 14, which matches exactly the given set {3,5,7,9,11,13}. Therefore, the correct option that represents the given set is (a).
