Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.341\% 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 additional words.
Options:
[a] CC1(C)Cc2nc(Cl)c(C(=O)O)cc2CO1
[b] CC(C)Cn1c(N)c(C(=O)COC(=O)Cc2cccs2)c(=O)n(C)c1=O
[c] CCOc1c(C)cc(S(=O)(=O)NCc2cccnc2)c(C)c1C
[d] COC(=O)c1ccccc1NC(=O)N1c2ccccc2Sc2ccccc21
[e] COc1ccc(N=Nc2c(O)[nH]c(=S)[nH]c2=O)cc1
Answer: a. CC1(C)Cc2nc(Cl)c(C(=O)O)cc2CO1
