This question places K on Friday morning. When a question gives you a new rule, you should always see how the new rule affects other rules.
In this case, we know that J must go with K or Q, and J must be in the morning (rule 1). So, J can’t go with K here: it must go with Q.
So JQ will either have to go on Wednesday or Thursday, with Q in the afternoon. Therefore I looked for answers that said “J W/T morning” or “Q W/T afternoon”.
Based on that, A looked possible. I drew a quick diagram to check:
This works, it obeys the NR rule and the rule that Q is before K and N. A is CORRECT.
C is wrong because Q must go in the afternoon.
B and E are wrong because one of either N or S needs to go with R, and be in the morning. And this pair must be on Wednesday or Thursday (So that K can go Friday).
JQ fills one of the Wednesday/Thursday slots. So, we need S/N and R, in the other slot, with S/N in the morning. Therefore, there’s no space to put S or N on Wednesday or Thursday afternoon.
D is wrong because R needs to go with N or S, not K.
These are the explanations for the wrong answers. But the real way to go quickly is to prephrase answers the way I did above. I was specifically looking for J on Wednesday or Thursday morning, or Q on Wednesday or Thursday afternoon. This process lets you answer much more quickly and confidently.
