Task: Answer the multiple-choice question.
Question: Which drug has a 21.619% 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) CN(Cc1ccccc1)C(=O)[C@@H]1CCCN1S(=O)(=O)c1ccc(Cl)cc1
b) O=C(CNC(=O)c1cccc(Br)c1)N/N=C/c1ccc2c(c1)OCO2
c) O=C(O)Cc1csc(-c2cccc(Oc3ccccc3)c2)n1
d) O=C(O)c1cnc(-c2ccccc2)nc1Sc1ccc(Cl)cc1
Answer: b. O=C(CNC(=O)c1cccc(Br)c1)N/N=C/c1ccc2c(c1)OCO2
