Task: Answer the multiple-choice question.
Query: Which drug exhibits a 11.812\% human ether-à-go-go related gene (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 COc1ccc(N2CCN(CC(=O)c3ccccc3)CC2)cc1
b O=C(Cc1ccccc1)NNC(=O)c1ccc(NC(=O)c2ccccc2)cc1
c COc1cccc(/C(O)=C2/C(=O)C(=O)N(CCN3CCOCC3)C2c2cccs2)c1
d COc1ccc(C2C(C#N)=C(N)Nc3nc4ccccc4n32)cc1
Answer: d. COc1ccc(C2C(C#N)=C(N)Nc3nc4ccccc4n32)cc1
