The correct answer is: A. direct
The word “baroque” is often used to describe something that is ornate, complex, and extravagant. The opposite of these qualities is “direct,” which means simple, straightforward, and unadorned.
The other options are not as good antonyms of “baroque” because they do not convey the same sense of simplicity and straightforwardness. For example, “straight” can refer to something that is physically straight, but it can also mean something that is honest or sincere. “Plain” can refer to something that is simple or unadorned, but it can also mean something that is dull or uninteresting. And “strong” can refer to something that is physically strong, but it can also mean something that is powerful or forceful.
In conclusion, the best antonym of “baroque” is “direct.”
