Task: Answer the multiple choice question.
Question: Which drug has a 2.891\% 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) C=CCN(CC=C)C(=O)Nc1cc(Cl)ccc1OC
b) O=C(Cn1cc2c(n1)CCCCC2)NCCN1CCOCC1
c) Cc1ccc(-n2nnnc2SCC(=O)c2c(N)n(CC(C)C)c(=O)n(C)c2=O)cc1
d) CCOc1ccc(N2C(=O)CC(Sc3ccccc3C(=O)O)C2=O)c([N+](=O)[O-])c1
Answer: d. CCOc1ccc(N2C(=O)CC(Sc3ccccc3C(=O)O)C2=O)c([N+](=O)[O-])c1
