Task: Answer the MCQ question.
Query: Which drug exhibits a -24.436% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) COc1ccc(-c2cc(=O)oc3c(C)c(OCC(=O)NCCCn4ccnc4)ccc23)cc1
b) COc1ccc(C(=O)C2CCCN(Cc3cn[nH]c3-c3ccc(F)cc3)C2)cc1OC
c) Cc1cc(C)n(/N=C/c2c[nH]c3ccccc23)c(=O)c1
d) O=c1cc(-c2ccccc2)c2ccc(O)cc2o1
e) CCc1cccc(NC(=O)CNC(=O)N2CC(=O)Nc3ccccc32)c1
Answer: d. O=c1cc(-c2ccccc2)c2ccc(O)cc2o1
