Task: Answer the multiple-choice question.
Question: Which drug has a 6.983\% 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 CCOC(=O)/C(C#N)=C/c1c(N2CCN(c3ccccc3)CC2)nc2ccccn2c1=O
b Cc1ccc(NC(=O)C2CCCCC2)cc1C
c O=C(c1ccc[nH]c1=S)N1CCN(S(=O)(=O)c2ccc(Br)cc2Cl)CC1
d COC(=O)CN1C(=O)C(C)(C)Oc2ccc(C(=O)Nc3cccc(OC)c3)cc21
Answer: c. O=C(c1ccc[nH]c1=S)N1CCN(S(=O)(=O)c2ccc(Br)cc2Cl)CC1
