Problem statement: Answer the MCQ question.
Query: Which drug exhibits a -2.825\% 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 other words.
Options:
[a] O=C(CN1C(=O)/C(=C/c2c(F)cccc2Cl)Oc2ccccc21)NCc1ccco1
[b] O=C(CSc1ccc2nnc(-c3ccc(F)cc3)n2n1)N1CCOCC1
[c] CCN(CC(=O)Nc1ccc(NC(C)=O)cc1)C(=O)Cc1ccccc1F
[d] Cn1cc(S(=O)(=O)Nc2ccc(Cl)cc2Cl)c(=O)n(C)c1=O
[e] CC(=O)c1ccc(OCCCC(=O)NNC(=O)c2ccccn2)cc1
Answer: b. O=C(CSc1ccc2nnc(-c3ccc(F)cc3)n2n1)N1CCOCC1
