Task: Answer the multiple choice question.
Question: Which drug has a 17.884\% 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(NCC1CCCO1)c1onc(CSc2cccc(Cl)c2)c1C(=O)O
b.) CCc1ccc(-c2nn(-c3ccccc3)cc2C2SCC(=O)N2Cc2ccco2)cc1
c.) CCc1ccc(N2C(=O)CC(N(CC3CCCO3)C(=O)/C=C/C(=O)O)C2=O)cc1
d.) Cc1ccc(Nc2cnn(C34CC5CC(CC(CC(=O)O)(C5)C3)C4)c(=O)c2Cl)cc1C
Answer: c. CCc1ccc(N2C(=O)CC(N(CC3CCCO3)C(=O)/C=C/C(=O)O)C2=O)cc1
