Task: Answer the multiple-choice question.
Query: Which drug has a -0.558\% 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 additional words.
Options:
a) CCC(CC)C(=O)Nc1ccccc1NC(C)=O
b) CCOC(=O)c1cnc(-n2nc(C)cc2C)nc1N(C)C
c) CCn1c(=N)c(S(=O)(=O)c2ccc(C)cc2)cc2c(=O)n3ccccc3nc21
d) CC1=CC(C)(C)n2c(O)c(C3=NC(=S)NC3=O)c3cc(OC(=O)c4cccc5ccccc45)cc1c32
e) O=C(Cc1cccs1)OCC(=O)c1ccco1
Answer: e. O=C(Cc1cccs1)OCC(=O)c1ccco1
