A
When
A = 0 = B
Q1 is low resistance,
Q2 is high resistance
A = 0, B = 0 =
Q5 = high, Q4 - low, Q3 – high, Q6 – low
A = 0, B = 1 => Q1 = high, Q2 = low, Q5 = high, Q4 = high, Q3 = low, Q6 = low, z = 1
A = 1, B = 0 => Q1 = low, Q2 = high, Q3 = high, Q4 = low, Q5 = low, Q6 = high, z = 0
A = 1, B = 1 => Q1 = high, Q2 = low, Q3 = high, Q4 = low, Q5 = low, Q6 = high, z = 0

Minterms are basically all possible combinations of a given set of boolean variables formed by the AND operation.
Maxterms are basically all possible combinations of a given set of boolean variables formed by the OR operation.
Minterms always output a 1, while maxterms output a 0.
Using minterms and maxterms, we can deduce a boolean expression from its truth table.
