Answer: “Sarah’s hands were cold and clammy” is a simple/declarative sentence.
Explanation: A simple or declarative sentence is a sentence that provides a statement. In declarative sentences, unlike in interrogative and imperative sentences, the subject is usually found in initial position, which means that the predicate generally comes after the subject. “Sarah’s hands were cold and clammy” is a simple sentence because it is declaring something, that is to say that it is expressing a statement and not a question or a command. Moreover, the subject ("Sarah's hands") has been placed in initial position.
