Task: Answer the MCQ question.
Question: Which drug exhibits a 4.087\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=C(NCC1CC1)C1CCCN(S(=O)(=O)c2ccc(-n3cnnn3)cc2)C1
(b) COc1cc2cc(C#N)c(SCC(=O)Nc3cc(C)on3)nc2cc1OC
(c) O=S(=O)(NCCc1csc(-c2ccc(C(F)(F)F)cc2)n1)c1ccc2c(c1)OCCO2
(d) CCOC(=O)COc1c(Cl)cc(C2NC(=S)NC(c3ccccc3)=C2C(C)=O)cc1OCC
(e) CC1Cn2c(nnc2-c2cccc(Cl)c2)S1
Answer: d. CCOC(=O)COc1c(Cl)cc(C2NC(=S)NC(c3ccccc3)=C2C(C)=O)cc1OCC
