Task: Answer the multiple-choice question.
Question: Which drug has a 16.629\% 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=C1C(c2c(O)[nH]c3ccccc23)=Nc2ccccc21
(b) Cc1ccc(C(=O)OCC(=O)Nc2ccc3c(c2)OCO3)o1
(c) O=C(CCS(=O)(=O)c1ccc(Br)s1)NCc1ccc2c(c1)OCO2
(d) COc1ccc(C(=O)Nc2ccc(O)cc2C(=O)O)cc1
Answer: d. COc1ccc(C(=O)Nc2ccc(O)cc2C(=O)O)cc1
