Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.039\% human ether-à-go-go related gene (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: CCOc1cc(CNCc2cc(OC)cc(OC)c2)ccc1OC.O=C(O)C(=O)O
b: COc1cc(/C=N/NC(=O)c2cc(-c3cccc(OC(C)C)c3)nc3ccccc23)ccc1O
c: C=C(c1ccccc1O)n1ccnc1
d: COC(=O)C1=C(C(C)=O)C(c2ccc(C)cc2)n2nnnc2N1
Answer: c. C=C(c1ccccc1O)n1ccnc1
