Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 16.501\% 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(C)NC(C)=C(C(=O)OCC)C1C(=O)OCC(=O)N(C)C1CCS(=O)(=O)C1
b O=C(NCC1CCCO1)NC1CCCCC1
c CC1CCC2(CC1)NC(=O)N(CC(=O)NC(C)c1ccc(F)c(F)c1)C2=O
d CCN1CCCC1CNC1=NCCCCC1
e CC1=NN(C(=O)CSCc2ccccc2)C(O)(c2ccccc2)C1
Answer: b. O=C(NCC1CCCO1)NC1CCCCC1
