The correct word to fill in the blank is "construed." When a constitutional amendment is construed, it means it is interpreted or understood in a particular way. The term "construed" specifically refers to the process of interpretation applied to constitutional amendments or legal text to clarify meaning.
Among the options "disparaged," "developed," "construed," and "enumerated," "construed" is the one that fits because amendments require interpretation to understand how they apply within the constitutional framework. Thus, the sentence reads: "When a constitutional amendment is construed, it is interpreted."
