What is the closest meaning of the word 'abstruse'?

• A. Strict
• B. To mistake for something else
• C. Chance of happening
• D. Difficult to understand

Answer: (D)

Abstruse describes something that is hard to understand because it’s obscure or highly complex. The closest meaning is that it is difficult to understand. For example, a dense theoretical paper with specialized notation can be abstruse, making its ideas hard for readers to grasp. The other options don’t fit: strict means rigid or exact, which isn’t about clarity; to mistake for something else refers to misidentification; and chance of happening concerns probability. So the best match is the idea of being difficult to understand.
