Why is B wrong? I totally get combining the conditional language but I'm trying to work on making sure that each incorrect answer is completely wrong. Thanks

Hi #JW, thanks for the question.

Answer choice B is incorrect because it allows previously unacceptable scenarios. It is more inclusive than the original rule, which is harder to spot than knocking out answer choices which are more restrictive than the original rules.

The original rule that we are trying to substitute for is the following:
NOT T1 (T7) - > R1
NOR R1 - > T1

While answer choice B does not restore the relationship between R and T when T is not in 1 (aka in 7). Based on the new rule, R becomes independent when T is in 7, when in the original rules are such that it should be firmly placed in slot 1.

Please let me know if this was helpful and feel free to ask any other questions you may have.
