Task: Answer the multiple-choice question.
Query: Which drug has a 8.377\% human ether-à-go-go related gene (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 O=C(CCn1c(=O)oc2ccccc21)NCCCN1CCCC1=O
b CCOc1cccc2sc(N(CCN(C)C)C(=O)c3ccc4ccccc4c3)nc12.Cl
c CCOC(=O)C1CCN(C(=O)c2cc3cc(F)ccc3[nH]2)CC1
d COc1cccc(NC(=O)CN(C)CC(=O)Nc2ccc(Cl)cc2[N+](=O)[O-])c1
Answer: a. O=C(CCn1c(=O)oc2ccccc21)NCCCN1CCCC1=O
