Task: Answer the MCQ question.
Question: Which drug has a 10.886\% 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 additional words.
Options:
a: O=C(COC(=O)c1nc(Cl)ccc1Cl)NC1CCS(=O)(=O)C1
b: COc1ccc(OC)c2c(C)c(C)[nH]c12
c: O=C(NCc1ccc(N2CCCC2=O)cc1)Nc1ccccc1
d: CC(C)CN1CCN(C(=O)CCc2nnc(Cc3c[nH]c4ccccc34)o2)[C@@H](C)C1=O
Answer: a. O=C(COC(=O)c1nc(Cl)ccc1Cl)NC1CCS(=O)(=O)C1
