The correct logic of the stimulus SHOULD BE:

healthy bones --> sufficient calcium == sufficient calcium --> /healthy bones

or

A --> B == /B --> /A

How the stimulus concludes it to be:

healthy bones --> sufficient calcium == /healthy bones --> /sufficient calcium

A --> B == /A --> /B

We are looking to match the flawed logic of A --> B == /A --> /B within the answer choices

A's logic (how the answer choice concludes it):

firm crust --> right temp == /right temp --> /firm crust

A --> B == /B --> /A

This answer choice is logically sound. However, this means we have 2 absolute reasons why we know A is not correct now.

1. We are looking for a FLAWED answer choice and A is not flawed.

2. The logic of A --> B == /B --> /A does not match the stimulus which provided the flawed logic of

   A --> B == /A --> /B

If A were to be correct it should have said "It therefore follows that bread that does not h

B on the other hand is both flawed and follows the same reasoning/conclusion

taste good --> right flour == /taste good --> /right flour

1. This answer choice is FLAWED

2. It matches the same chain of logic

Therefore B is the correct answer.

tldr: basically the stimulus provides a logic chain that is flawed. when i was doing the question I read that A had the same amount of conditions and structure but the conclusion was logically sound (not flawed) so A must be wrong. B on the other hand had the same condition and structure but the conclusion logic was flawed in the same structure as the stimulus.
