Task: Answer the multiple choice question.
Question: Which drug has a 5.519\% 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] O=c1cnc2ccccc2n1CC1CCCCC1
[b] Cc1cc(Nc2ccc(Cl)cc2)n(-c2ccccc2)n1
[c] Cc1cc(C)nc(N2CCC(C(=O)Nc3cccc(C(F)(F)F)c3)CC2)n1
[d] O=C(NCCc1ccccc1)c1ccc(NCC2CCCO2)c([N+](=O)[O-])c1
[e] COc1ccc2c(c1)c1ncnc(N(C)C)c1n2C
Answer: b. Cc1cc(Nc2ccc(Cl)cc2)n(-c2ccccc2)n1
