Rectify means to which of the following?

• A. Correct (something that is wrong) or make something right or better
• B. Correct by calculation or adjustment
• C. To repair hair
• D. To align gears

Answer: (A)

Rectify means putting something that’s wrong back in its proper state. In everyday use, it’s about correcting or fixing a mistake, making things right or better. That’s why the description that says to correct something that is wrong or to make it right or better is the best fit. In some technical contexts, rectify can mean to correct by calculation or adjustment, but that sense is narrower and less common in general vocabulary. The other options describe things that aren’t about correcting or making things right, so they don’t capture the broad meaning of rectify.
