Question

complete the sentence with the word that best fits the overall meaning and tone. \has anyone ________ his alibi, or should we still consider him a suspect?\ the detective asked. corroborated denounced announced

Explanation:

"Corroborated" means to confirm or give support to (a statement, theory, or finding). In the context of the detective's question, it makes sense as the detective is asking if anyone has confirmed the suspect's alibi. "Denounced" means to publicly declare to be wrong or evil, which doesn't fit the context. "Announced" simply means to make a public or formal declaration, which is also not appropriate here as the focus is on verifying the alibi.

Answer:

corroborated
