Problem statement: Answer the multiple-choice question.
Query: Which drug has a 1.853\% 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(O)CN1CCN(Cc2ccccc2Cl)C1=O
b.) CCOc1ccc(N(CC(=O)NCc2ccccc2Cl)S(=O)(=O)c2c(C)noc2C)cc1
c.) CC(=O)Nc1nnc(CCS(=O)(=O)c2ccc(C)c(C)c2)s1
Answer: a. O=C(O)CN1CCN(Cc2ccccc2Cl)C1=O
