Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.810\% 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 additional words.
Options:
a.) NC(=O)CSc1ncc(-c2ccc([N+](=O)[O-])cc2)[nH]1
b.) Cn1c(SCC(=O)Nc2cccc(S(=O)(=O)NC3=NCCCCC3)c2)nnc1-c1ccncc1
c.) COc1cc(C2=NOC(C(=O)Nc3ccc4c(c3)OCO4)C2)cc(OC)c1OC
d.) O=C(NC1CCCCC1)c1cccc(COCC(F)(F)F)c1
Answer: a. NC(=O)CSc1ncc(-c2ccc([N+](=O)[O-])cc2)[nH]1
