Task: Answer the multiple-choice question.
Query: Which compound exhibits a 5.206% 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 additional words.
Options:
a O=C1OC(C(=O)O)Cc2ccccc21
b CCOC(=O)c1nn(-c2ccc(Cl)cc2C)ccc1=O
c O=S(=O)(c1ccc(Cl)cc1)N1CCCC1c1cccnc1
d COc1ccccc1N1CCN(CC(O)COCCOc2ccc(Br)cc2)CC1.Cl
Answer: a. O=C1OC(C(=O)O)Cc2ccccc21
