Task: Answer the MCQ question.
Query: Which compound exhibits a 9.808\% 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, or d without using any other words.
Options:
(a) COc1ccc(C2CC(c3ccc(F)cc3)Nc3nc(N)nn32)cc1OC
(b) C/C(N)=C(/C#N)C(=O)CSc1nc2ccccc2c(=O)n1-c1ccc(C)c(Cl)c1
(c) O=C(c1ccc(Cl)c(Cl)c1)N1CCC(=O)N(C(COCc2cccc(Cl)c2)Cc2ccccc2)CC1
(d) CC1(c2nnc(-c3ccccc3)o2)CC(c2c(Cl)cccc2Cl)=NO1
Answer: b. C/C(N)=C(/C#N)C(=O)CSc1nc2ccccc2c(=O)n1-c1ccc(C)c(Cl)c1
