I can understand "buts" means "objection" here, but can't get what c)tales or d)picks means. Are c and d nonsense or do they have any similar meanings?
Q. Choose the right answer
A:I can't tell Meg her dress looks great when it looks awful
B:Well, I have no __a___ about lying so that she doesn't get upset.
a)qualm
b)buts
c)tales
d)picks
c and d are nonsense and you're barking up the wrong tree if you are trying to make "buts" fit there.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
I'm used to seeing "qualms" rather than "qualm" in a situation like this.
