Task: Answer the multiple choice question.
Question: Which drug has a 17.396\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(CSc1ccc(-c2ccc(Br)cc2)nn1)NCC1CCCO1
b COc1ccc(S(=O)(=O)N2CCCC(C(=O)NCC3CCCO3)C2)cc1Cl
c CC(C)(C)c1ccc(OCC(=O)N2CCCCCC2)c(Br)c1
d O=C(N/N=C/c1cn(-c2ccccc2)nc1-c1cc2ccccc2o1)c1c[nH]c2ccccc12
Answer: a. O=C(CSc1ccc(-c2ccc(Br)cc2)nn1)NCC1CCCO1
