Final answer:
The sentence contains an uncontactable form of the copula BE followed by an adverbial of place, making it true that it contains an obligatory context for the uncontactable copula.
Step-by-step explanation:
The sentence "I am here to fix your sink" does indeed contain an obligatory context for the uncontactable copula BE (am, are, is, was, were). The sentence contains an uncontractible form of the copula BE followed by an adverbial of place, making it true that it contains an obligatory context for the uncontractible copula.
It follows the sentence pattern where the be verb serves as the main verb and is immediately followed by an adverbial of time or place, fulfilling pattern number 1: (subject)+(be verb)+(adverbial of time or place). In this case, "I" is the subject, "am" is the uncontractible form of the verb BE, and "here" serves as the adverbial of place, making statement A (True) the correct option.
