can someone explain why B is true?

Let's take a look at (B). (B) says, "Scientists generally do not now believe that classical Euclidean geometry is uniquely capable of giving a correct mathematical representation of the universe." (B) tells us that most scientists believe that a non-Euclidian representation of the universe is something that's possible. This statement is supported by the strong claim in the stimulus when it states that scientists think that a representation of the universe using non-Euclidian geometry is more useful for some areas of scientific theory. Thus, (B) is the correct answer choice, as it's the answer choice that's most strongly supported b the stimulus. Does this make sense? Let us know if you have any other questions!
