Task: Answer the multiple choice question.
Query: Which compound has a 18.697\% 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/c1ccccc1)c1ccc(-c2ccccc2)cc1
b) COc1ccccc1CNS(=O)(=O)c1c(C)[nH]c(C)c1C(=O)N1CCCC1
c) N#Cc1c(NCCCO)nc(-c2ccccc2)c2c1CCCC2
d) CC(C)OC(=O)CSc1nc(C(C)C)nc2ccccc12
e) Cc1c(Cl)cccc1NCC(=O)Nc1ccc(Cl)cc1F
Answer: a. O=C(N/N=C/c1ccccc1)c1ccc(-c2ccccc2)cc1
