How is the condition "A can come neither immediately before nor immediately after B" expressed in formal logic?

AB
BA
AB BA (With line through them)
BA AB (With line through them)

The correct answer is: AB BA (With line through them)

In formal logic, the condition "A can come neither immediately before nor immediately after B" is expressed by writing AB and BA with a line through them. This notation indicates that the order AB and the order BA are not permissible according to the given condition. This is because A cannot be immediately before B or immediately after B, hence eliminating the possibilities of AB and BA. Therefore, option C is the correct way to express this restriction in formal logic.
