Task: Answer the multiple choice question.
Question: Which compound exhibits a -65.348% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(COc1ccccc1Br)NCCc1nc2ccccc2[nH]1
b. COc1cc([C@@H]2CC=C(C(=O)O)CN2S(=O)(=O)c2ccc(C)cc2)cc(OC)c1OC
c. COc1ccc(NC(=O)c2cc(-c3ccc4c(c3)OCO4)on2)cc1
d. Cc1onc(-c2ccccc2)c1CNC(=O)CN1C(=O)c2ccccc2C1=O
Answer: a. O=C(COc1ccccc1Br)NCCc1nc2ccccc2[nH]1
