Task: Answer the multiple-choice question.
Question: Which drug exhibits a 0.170\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CN(C)C(=O)CSC1c2ccccc2C(=O)N1c1ccccc1
b CCC1CCCCN1C(=O)c1ccc(OC)c(OC2CCN(C(C)C)CC2)c1
c O=C(c1ccc(Cn2c(=O)[nH]c3ccccc3c2=O)cc1)N1CCN(c2ccccn2)CC1
d CN(C)c1ccc(C(=O)/C=C/c2ccccc2)cc1
Answer: c. O=C(c1ccc(Cn2c(=O)[nH]c3ccccc3c2=O)cc1)N1CCN(c2ccccn2)CC1
