Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.408\% 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 additional words.
Options:
a: O=C(Nc1cnccn1)C1c2ccccc2Oc2ccccc21
b: O=C(O)c1ccccc1NS(=O)(=O)c1ccc2ccccc2c1
c: O=C(O)c1ccc(NC(=O)c2cccc(C(=O)Nc3ccc(C(=O)O)cc3)c2)cc1
d: CC(=O)O.NC(N)=N/N=C/c1c(Cl)cccc1Cl
Answer: b. O=C(O)c1ccccc1NS(=O)(=O)c1ccc2ccccc2c1
