Task: Answer the MCQ question.
Question: Which compound has a 15.647\% 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 COC(=O)CCC(=O)OC1(C)C(=O)C=C2C=C(C3CC3)N(CCc3ccccn3)C=C2C1=O
b O=C1c2ccccc2NC(c2ccco2)N1/N=C/c1ccco1
c CCOC(=O)C1=C(COC(=O)/C=C/c2cc(OC)c(OC)c(OC)c2)NC(=O)NC1C
d CCOC(=O)c1c(-c2ccc(C)o2)csc1NC(=O)CN1CCOCC1
Answer: c. CCOC(=O)C1=C(COC(=O)/C=C/c2cc(OC)c(OC)c(OC)c2)NC(=O)NC1C
