Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 6.192\% 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=S(=O)(NC1Cc2ccccc2C1)c1ccccc1
b O=c1c2sccc2[nH]c(=S)n1-c1ccccc1
c Cc1ccnc(NC(=O)CCc2c[nH]c3ccccc23)c1
d O=C(Nc1cccnc1)c1ccc(NS(=O)(=O)c2cc([N+](=O)[O-])ccc2Cl)cc1
Answer: b. O=c1c2sccc2[nH]c(=S)n1-c1ccccc1
