Deduce the waveform at the Q output of the following circuit.

My solution is in blue. For Q to be high, EN must be high and R and S must be opposite. The answer is wrong, so obviously there's sth wrong with my reasoning as well...

In any case (either NOR or NAND) the output here would be high only when one input is high (either S or R).
