Inept can mean not effective.

• A. not effective
• B. unimportant
• C. inexperienced
• D. well coordinated

Answer: (A)

The main idea here is recognizing a word that describes a lack of skill or competence leading to poor results. Inept means someone is not capable or skilled enough to do something well, so the outcome tends to be not effective. That’s why the corresponding meaning fits best: not effective.

Think of inept as pointing to the quality of performance—if you’re inept, the task doesn’t get done effectively. The other options miss this direct sense: unimportant refers to significance, not ability; inexperienced points to a lack of experience but doesn’t necessarily imply failure to achieve results; well coordinated describes smooth, effective action, which is the opposite of inept.
