Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 5.509\% 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] O=C(C1CCCN(S(=O)(=O)Cc2ccccc2)C1)N1CCCCC1
[b] COC(=O)c1cc(S(=O)(=O)C(C)C)c(S(C)=O)s1
[c] Cc1ccc2c(c1)C(=O)c1ccccc1CS2=O
[d] COc1ccc2cc(CCOC3CCCCO3)ncc2c1
Answer: a. O=C(C1CCCN(S(=O)(=O)Cc2ccccc2)C1)N1CCCCC1
