Task: Answer the multiple choice question.
Question: Which drug has a 2.641\% 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 other words.
Options:
a: CCOC(=O)C1=C(CC)Nc2ccccc2N=C1NC(=O)c1cc(C)on1
b: C/C(=N\Nc1ccc2nncn2n1)c1cccs1
c: COc1ccc(C2=CC(c3ccc(F)cc3)n3nnnc3N2)cc1
d: CSc1ccc(CNc2ccc(C)cc2)cc1
e: Cc1ccc(/C=C2\CCOC2=O)cc1
Answer: e. Cc1ccc(/C=C2\CCOC2=O)cc1
