Task: Answer the multiple-choice question.
Question: Which drug exhibits a 19.061\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a Cc1ccc(NC(=O)c2ccc(=O)[nH]n2)cc1C
b CCOc1ccccc1N(CC(=O)Nc1cccnc1)S(C)(=O)=O
c O=c1oc2ccccc2cc1-c1ccc(O)cc1O
d Cc1ccc(C(=O)NNc2cc(N3CCCC3)nc(N3CCCC3)n2)cc1
Answer: b. CCOc1ccccc1N(CC(=O)Nc1cccnc1)S(C)(=O)=O
