Problem statement: Answer the multiple choice question.
Query: Which drug has a 18.316\% 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, or c without using any other words.
Options:
a) O=C(OCc1nnc(-c2ccccc2)o1)c1ccc(CO)cc1
b) Cc1ccc(S(=O)(=O)N(C)C)cc1NS(=O)(=O)c1ccc(Cl)s1
c) Cc1c(C(=O)NCCS(=O)(=O)N2CCN(c3ccccc3F)CC2)cccc1[N+](=O)[O-]
Answer: a. O=C(OCc1nnc(-c2ccccc2)o1)c1ccc(CO)cc1
