Task: Answer the multiple choice question.
Query: Which compound exhibits a 11.832\% 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, d, or e without using any other words.
Options:
a.) C/C(=N\NC(=O)c1ccc(Br)o1)c1cc2c(cc1NC(=O)CCC(=O)O)OCO2
b.) Cl.O=c1[nH]oc2c1CCNC2
c.) CCC(CC)C(=O)Nc1nnc(SCC(=O)NC2CC2)s1
d.) COc1ccc(S(=O)(=O)N(C)CC(=O)N2CCCC2)cc1Cl
e.) O=C(OCC(=O)N1CCC(c2ccccc2)=N1)c1ccc([N+](=O)[O-])s1
Answer: b. Cl.O=c1[nH]oc2c1CCNC2
