Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 19.159\% 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=[N+]([O-])c1ccc2nc(-c3ccc(Cl)cc3)n(OCc3ccccc3)c2c1
b.) C=CCNC(=O)c1onc(CSc2ccc(Cl)cc2)c1C(=O)NCC=C
c.) Cc1ccccc1-n1c(SCC(=O)Nc2ccccc2)nc2nc3c(cc2c1=O)CCCC3
d.) COc1cccc(OC)c1C(=O)N1CCN(Cc2cccnc2)CC1
e.) N#Cc1c(N)nc(SCc2ccccc2)c(C#N)c1-c1ccco1
Answer: a. O=[N+]([O-])c1ccc2nc(-c3ccc(Cl)cc3)n(OCc3ccccc3)c2c1
