Task: Answer the multiple choice question.
Question: Which compound has a 19.977% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) C=CCc1cc(/C=C2/NC(=O)NC2=O)cc(OCC)c1O
(b) CCCc1cc2c(cc1NC(=O)c1ccc(C)cc1)OCO2
(c) CC(=O)Nc1ccc(S(=O)(=O)NCC2CCCO2)cc1
(d) CCOc1cc2[nH]c(=S)n(CCCC(=O)N3CCC4(CC3)OCCO4)c(=O)c2cc1OCC
Answer: a. C=CCc1cc(/C=C2/NC(=O)NC2=O)cc(OCC)c1O
