Task: Answer the MCQ question.
Question: Which drug exhibits a 4.421% 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, or d without using any additional words.
Options:
a: CC(C)(C)C1=C(C#N)C(c2cccnc2)C(C#N)=C(N)O1
b: COc1cc(C(=O)Nc2ccccc2NC(=O)c2cc(OC)c(OC)c(OC)c2)cc(OC)c1OC
c: COc1cccc(NC(=O)C2CCCN(S(=O)(=O)c3cccc4cccnc34)C2)c1
d: CC(C)(C(N)=O)N1CCN(c2ncc(C(F)(F)F)cc2Cl)CC1
Answer: a. CC(C)(C)C1=C(C#N)C(c2cccnc2)C(C#N)=C(N)O1
