Task: Answer the multiple choice question.
Query: Which drug has a -2.561\% 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 other words.
Options:
a) CCCn1nc([N+](=O)[O-])c(C(C#N)c2nc3ccccc3o2)c(Cl)c1=O
b) CCN1CCN(S(=O)(=O)c2ccc(OC)c(Br)c2)CC1
c) COCCNC(=O)CN(Cc1ccc(Cl)cc1)S(C)(=O)=O
d) COc1ccc(CSCCc2n[nH]c(=S)n2-c2ccccc2)cc1
Answer: c. COCCNC(=O)CN(Cc1ccc(Cl)cc1)S(C)(=O)=O
