Task: Answer the multiple choice question.
Query: Which drug exhibits a -3.756\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(c1ccc(CNc2c(N3CCCC3)c(=O)c2=O)cc1)N1CCc2ccccc2C1
b) O=P(Nc1nc2ccc(Cl)cc2s1)(c1ccccc1)c1ccccc1
Answer: a. O=C(c1ccc(CNc2c(N3CCCC3)c(=O)c2=O)cc1)N1CCc2ccccc2C1
