Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.533\% 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=C(N/N=C/c1cc(Br)ccc1OC(=O)c1ccc(Br)cc1)c1ccncc1
[b] O=C(CSCc1ccc(F)cc1)NC1CCCC1
[c] CCN1CCN(c2nc3c(c(=O)n(C)c(=O)n3C)n2CCSc2ncccn2)CC1
[d] COc1ccc(-c2cnc(SCC(=O)Nc3cc(C)on3)n2Cc2ccco2)cc1
[e] NC(=O)c1cc(-c2ccccc2)nc(N2CCCCCC2)n1
Answer: c. CCN1CCN(c2nc3c(c(=O)n(C)c(=O)n3C)n2CCSc2ncccn2)CC1
