Problem statement: Answer the multiple-choice question.
Query: Which drug has a 19.858\% 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 additional words.
Options:
a.) O=C1OC(Oc2ccccc2)(c2ccccc2)c2ccccc21
b.) COc1ccc(C)cc1S(=O)(=O)Nc1cccnc1
c.) O=C(CNC(=O)c1ccc(F)cc1)N/N=C/c1ccc(O)c([N+](=O)[O-])c1
d.) CCn1c(CNc2ccc(C)cc2)nnc1SCC(N)=O
e.) CCOc1ccc(Cl)cc1CNCCNCCO.Cl
Answer: e. CCOc1ccc(Cl)cc1CNCCNCCO.Cl
