Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 12.924% 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, d, or e without using any additional words.
Options:
[a] CC1C2C(c3ccccc3)N(C)C(=O)N(C)C2N(C)C(=O)N1C
[b] Cc1ccc(NC(=O)C[n+]2cc(-c3ccc(C)cc3)n3c2CCC3)cc1.[Cl-]
[c] Cc1nn(-c2ccccc2)nc1C(=O)NNC(=O)c1cccc2ccccc12
[d] CCOC(=O)Cc1csc(NC(=O)COc2ccccc2OCC)n1
[e] Cc1c(Cl)cccc1NC(=O)Cn1nc(C)n2cccc2c1=O
Answer: a. CC1C2C(c3ccccc3)N(C)C(=O)N(C)C2N(C)C(=O)N1C
