Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.339\% 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 additional words.
Options:
a) Nc1n[nH]c2cc(=O)n(-c3cccc(C(F)(F)F)c3)nc12
b) CC(C)(C)c1ccc(OCC(=O)Nc2ccc(-c3nc4cccnc4o3)cc2)cc1
c) CC(C)(C)c1ccc(NC(=O)CN2C(=O)NC(C)(C3CC3)C2=O)cc1
d) CNC(=S)N1CCN(CCN=Cc2c(O)n(-c3ccc(C)cc3)c(=S)[nH]c2=O)CC1
Answer: a. Nc1n[nH]c2cc(=O)n(-c3cccc(C(F)(F)F)c3)nc12
