Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.275\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. O=C1/C(=C/c2ccccc2)Nc2ccccc21
b. O=C(O)c1ccc(-[n+]2c(-c3ccccc3)cc(-c3ccccc3)cc2-c2ccccc2)cc1.[O-][Cl+3]([O-])([O-])[O-]
c. CCC(C(=O)Nc1nccs1)c1ccccc1
d. Cc1ccccc1OCC(=O)N/N=C/c1ccc(N2CCOCC2)o1
Answer: a. O=C1/C(=C/c2ccccc2)Nc2ccccc21
