Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.524% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. COc1ccc(/C(C)=N/NC(=O)c2sccc2-n2cccc2)cc1
b. C/C(=N\NC(=O)Cn1cc([N+](=O)[O-])cn1)c1ccc(O)cc1
c. O=C1NC2(CCCCCC2)N=C1c1ccc(Br)cc1
d. O=C(CSc1ccccc1NS(=O)(=O)c1ccc(Cl)cc1)Nc1nnc(C(F)(F)F)s1
Answer: c. O=C1NC2(CCCCCC2)N=C1c1ccc(Br)cc1
