Task: Answer the multiple choice question.
Query: Which drug has a 21.117\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. COC(=O)C1=C(C)NC(C)=C(C(=O)OC)C1c1ccc(C)o1
b. Cc1cc(C)c2nc(NC(=O)c3ccc([N+](=O)[O-])o3)sc2c1
c. O=C1CC(N2CCN(Cc3ccccc3)CC2)C(=O)N1
d. N#Cc1c(N)n(-c2ccc(O)cc2)c2nc3ccccc3nc12
Answer: b. Cc1cc(C)c2nc(NC(=O)c3ccc([N+](=O)[O-])o3)sc2c1
