Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 5.064\% 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: C=CCNCCCCOc1ccccc1.O=C(O)C(=O)O
b: CCOc1ccc2[nH]c(SCC(=O)OC)c([N+](=O)[O-])c2c1
c: NC(Cc1ccccc1)c1nc(-c2ccccc2)no1
d: CC(C)(C)n1ncc2c(=O)n(CC(=O)NCc3ccc4c(c3)OCO4)cnc21
e: CCOc1ccc(C(=O)NCC(=O)Nc2ccncc2)cc1OCC
Answer: a. C=CCNCCCCOc1ccccc1.O=C(O)C(=O)O
