Task: Answer the multiple choice question.
Question: Which drug has a 9.648\% 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) Cc1ccc(C(=O)N2CCN(S(=O)(=O)c3ccc(C)cc3)CC2)cc1
b) CCOc1ccc(C2=NNC(c3cccs3)=Nc3ccc(OC)cc32)cc1
c) O=C1C(=O)c2ccccc2-c2ccccc21
d) O=C(O)c1ccc(N/N=C/c2ccc3c(c2)OCO3)cc1
Answer: c. O=C1C(=O)c2ccccc2-c2ccccc21
