Final answer:
The interpretation of a contract of adhesion with complicated language is typically in favor of the drafter of the contract.
Step-by-step explanation:
The answer to the question is a) The drafter of the contract.
A contract of adhesion is a standard form contract that is presented to one party on a take-it-or-leave-it basis, with little to no opportunity for negotiation. These contracts often contain complicated language that may not be easily understood by the party adhering to the contract. As a result, courts generally interpret ambiguous or unclear terms in a contract of adhesion in favor of the party who drafted the contract.
