Why is AC E incorrect?

Can someone explain why C is wrong?

I get why E is right but can someone explain why B is wrong?

Can someone please explain this and the flaw present?

#Help If a question is flawed by analogy, does the answer need to be as well? Similarly, with other flaws as well?

Can someone please explain why A is wrong and B is right. This is how I mapped it out:

Question:

Healthy Bones -> Sufficient Calcium (A->B)

Not Healthy Bones -> Not Sufficient Calcium (NOT A -> NOT B)

For answer choice A:

Firm crust -> baked at right temp (A->B)

Not baked at right temp -> not firm crust (Not B->Not A)

For answer choice B:

Right amount of flour -> taste good (A->B)

Does not taste good -> not right amount of flour (Not B->Not A)

are these not the same?

#HELP #FEEDBACK

Does anyone know if the stimulus is written in conditional language than the correct answer must also be written conditionally (meaning if/then)?

Can someone please explain in simple terms why E is correct?
