Task: Answer the MCQ question.
Query: Which drug has a 8.867\% 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. CC1=C(C#N)C(c2ccccc2)C2=C(N1)c1ccccc1C2=O
b. Cc1ccccc1NC(=O)/C(C#N)=C/c1ccccc1C(F)(F)F
c. COc1ccc(OC)c(/C=N/n2c(-c3n[nH]c4c3CCC4)n[nH]c2=S)c1
d. COc1cccc(NC(=O)CCC2CCN(C(=O)c3sccc3C)CC2)c1
Answer: a. CC1=C(C#N)C(c2ccccc2)C2=C(N1)c1ccccc1C2=O
