Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.038\% 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.) CC1CCN(C(=O)CSc2nnc(CNC(=O)c3ccc(S(=O)(=O)N(C)C)cc3)o2)CC1
b.) Cc1nn(C(C)(C)C)c(OC(=O)c2ccc3c(c2)OCO3)c1Sc1ccccc1
c.) OC/C(Br)=C(\Br)CO
d.) CCn1nnnc1SCC(=O)c1ccc2c(c1)OCCO2
Answer: c. OC/C(Br)=C(\Br)CO
