One of the statements below contains a word used incorrectly. Choose the option which has the incorrect or inappropriate usage of the word.

The question is testing for word usage between collaborate and corroborate.

When you collaborate with someone, you're working together like a team on a project. Think of it like being lab partners in science class - you're both mixing chemicals and taking notes together to complete the experiment. You collaborate WITH people ON something.

To corroborate means to back up or confirm something with evidence, like when your friend corroborates your alibi by telling the teacher that yes, you really were in the library during lunch when someone was drawing on the chalkboard. You corroborate statements, theories, or findings.

Option 1 -> Correct usage. The women refused to work together/cooperate in the protest.

Option 2 -> Correct usage. The relatives worked together with the British Empire.

Option 3 -> Incorrect usage. She should "corroborate" her thesis with evidence from interviews, not "collaborate" her thesis.

Option 4 -> Correct usage. The policeman worked together with the filmmakers.

Hence, Option 3 is correct
