Task: Answer the multiple choice question.
Question: Which drug has a -2.673\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCN(CC)c1ccc(/C=C2\C(=O)c3ccc(C(=O)O)cc3C2=O)cc1
b: Cc1nn(C)cc1C(C(=O)NC1CCCCC1)N(C(=O)c1cnccn1)c1ccc(Oc2ccccc2)cc1
c: Cc1ccc(NC(Cc2cc(C)no2)c2ccccc2)cc1
d: CC1(C)CC(N2CCCC2)=CC(=[N+]2CCCCC2)C1.[I-]
Answer: c. Cc1ccc(NC(Cc2cc(C)no2)c2ccccc2)cc1
