Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.129\% 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 or b without using any other words.
Options:
[a] O=C(CSc1nc2[nH]c(=O)cc(O)c2s1)Nc1cc(Cl)cc(Cl)c1
[b] Cc1c(C(=O)N2CCCCC2)c(S(=O)(=O)N2CCC(C)CC2)c(C)n1C
Answer: a. O=C(CSc1nc2[nH]c(=O)cc(O)c2s1)Nc1cc(Cl)cc(Cl)c1
