Task: Answer the MCQ question.
Question: Which drug has a 10.234\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: Cc1ccc(CNC(=O)C2CC(c3ccccc3F)=NO2)cc1
b: CCOc1cc(C2C(C#N)=C(N)OC(C)=C2C(C)=O)cc(Br)c1O
c: COc1ccc(OC)c(S(=O)(=O)N2CCN(C34CC5CC(CC(C5)C3)C4)CC2)c1
d: C=CCN(CC=C)Cc1c(O)ccc2c1oc(=O)c1ccccc12
e: Cc1occc1C(=O)NNC(=O)CN1C(=O)NC(C)(c2ccccc2)C1=O
Answer: b. CCOc1cc(C2C(C#N)=C(N)OC(C)=C2C(C)=O)cc(Br)c1O
