Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 0.476\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=C(NCC12CC3CC(CC(C3)C1)C2)c1nn2c(c1Cl)NC(c1ccco1)CC2C(F)(F)F
b. CCOC(=O)c1[nH]c(C)c(/C(O)=C2\C(=O)C(=O)N(CCCN3CCOCC3)C2c2cccs2)c1C
c. Cc1cccc2c(C(=O)O)c3cccc(C)c3nc12
Answer: b. CCOC(=O)c1[nH]c(C)c(/C(O)=C2\C(=O)C(=O)N(CCCN3CCOCC3)C2c2cccs2)c1C
