Task: Answer the MCQ question.
Question: Which drug has a 8.303\% 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: Cc1cn(C2OC(COC(=O)c3ccccc3)C(O)C2Cl)c(=O)[nH]c1=O
b: COc1ccnc(NCc2ccc(Cl)cc2)c1C#N
c: COc1ccc(-c2nnc(SC(C(=O)c3c[nH]c4ccccc34)c3ccccc3)n2N)cc1OC
d: O=C1NC(c2cc(Cl)cc([N+](=O)[O-])c2O)Nc2ccccc21
e: COC(=O)c1ccc(C2C(C#N)=C(N)Oc3cc(N)ccc32)cc1
Answer: a. Cc1cn(C2OC(COC(=O)c3ccccc3)C(O)C2Cl)c(=O)[nH]c1=O
