Task: Answer the multiple choice question.
Question: Which compound has a 25.238\% 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 other words.
Options:
[a] COc1ccc(C(C)(C)C)cc1NC(=O)CCN1C(=O)C2CCCCC2C1=O
[b] Cc1ccc(-c2n[nH]c(=S)n2/N=C/c2cc3c(cc2[N+](=O)[O-])OCO3)cc1
[c] C=CCNc1nc(NCCO)nc(N2CCCC2)n1
[d] O=c1c(C(c2ccc(Br)cc2)c2c(O)nc3n(c2=O)CCS3)c(O)nc2n1CCS2
Answer: a. COc1ccc(C(C)(C)C)cc1NC(=O)CCN1C(=O)C2CCCCC2C1=O
