Task: Answer the multiple-choice question.
Question: Which drug has a 2.736\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(Cn1nnc2ccccc21)N1CCCCC1
b: O=C(NCc1ccccc1)C1CCCN1S(=O)(=O)c1ccc(Cl)cc1
c: Cc1cccc(C)c1NC(=O)/C(C#N)=C/c1ccc(-c2ccc(C(=O)O)cc2)o1
Answer: a. O=C(Cn1nnc2ccccc21)N1CCCCC1
