Task: Answer the multiple choice question.
Question: Which compound exhibits a -19.039% 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(CNC(=O)c1ccco1)NCC(=O)OC(C(=O)c1ccccc1)c1ccc(Cl)cc1
b) O=C(c1ccc(O)cc1)c1ccc(Cl)cc1
c) COCCn1c(C)cc(C(=O)COC(=O)c2ccc3c(c2)NC(=O)CS3)c1C
d) CC(CCc1ccccc1)NC(=O)c1ccncc1
Answer: b. O=C(c1ccc(O)cc1)c1ccc(Cl)cc1
