Task: Answer the multiple-choice question.
Query: Which drug exhibits a 6.419\% human ether-à-go-go related gene (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 N#C/C(C(=O)NCc1ccccc1)=C1\SC(CCO)C(=O)N1c1ccccc1
b COc1ccc(-c2c(NC(=O)C(C)C)n(C)c3ccccc3c2=O)cc1
c CC1CCCC(NC(=O)CCCn2c(=O)[nH]c3cc(Cl)ccc3c2=O)C1C
d O=C(OCC(=O)N1CCN(c2ccccc2)CC1)c1ccc(O)cc1O
Answer: a. N#C/C(C(=O)NCc1ccccc1)=C1\SC(CCO)C(=O)N1c1ccccc1
