Task: Answer the multiple-choice question.
Query: Which drug exhibits a -0.318\% 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.) Cn1c(N/N=C2\CCCc3ccccc32)nc2c1c(=O)n(Cc1ccccc1)c(=O)n2C
b.) CC1(C)CC(=O)C(C=Nc2ccc(C(=O)c3ccccc3)cc2N=CC2=C(O)CC(C)(C)CC2=O)=C(O)C1
c.) COc1ccc(OC)c(C2C(C(=O)c3ccccc3)=C(C)Nc3nc4ccccc4n32)c1
d.) CCc1ccc(NC(=O)CCS(=O)(=O)c2ccc(Cl)cc2)cc1
Answer: a. Cn1c(N/N=C2\CCCc3ccccc32)nc2c1c(=O)n(Cc1ccccc1)c(=O)n2C
