Task: Answer the multiple choice question.
Question: What is the hERG inhibition at a concentration of 10uM of a drug with the SMILES CCCCc1c(O)nc(SCC(=O)N2CCOCC2)[nH]c1=O?
Constraint: You must return none, one or more options from a, b, c, or d without using any other words.
Options:
[a] 7.436
[b] -4.693
[c] 9.573
[d] -2.642
Answer: c. 9.573%.
