Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.964\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCOc1ccc(OCc2ccc(C(=O)Nc3cccc(C)n3)o2)cc1
b: Cc1ccc(NC(=O)/C(=C\c2cccc(Br)c2)NC(=O)c2ccco2)cc1
c: COc1cccc(N=CC2=C(O)CCCC2=O)c1
d: COc1ccc(CNc2nccs2)cc1OC
e: Br.O=[N+]([O-])c1ccc(CSC2=NCCN2)cc1
Answer: c. COc1cccc(N=CC2=C(O)CCCC2=O)c1
