Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 9.680\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(NCCCCNC(=O)c1ccccc1Cl)c1ccccc1Cl
b: Cn1c(/C=C/c2ccc(Cl)cc2)nc2ccccc2c1=O
c: CN(C[C@H](CC1CCCCC1)N(C[C@H](Cc1ccccc1)N(CCc1ccccc1)N=O)N=O)N=O.[Na+]
Answer: a. O=C(NCCCCNC(=O)c1ccccc1Cl)c1ccccc1Cl
