Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -1.277\% 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 other words.
Options:
a. C/C(=C\C(=O)c1ccncc1)Nc1ccccc1O
b. O=C(COC(=O)c1ccccc1)NCC1CCCO1
c. COCC(=O)OC/C(O)=C(\C#N)c1nc2ccccc2[nH]1
Answer: b. O=C(COC(=O)c1ccccc1)NCC1CCCO1
