Task: Answer the multiple choice question.
Query: Which drug exhibits a 21.356\% human ether-à-go-go related gene (hERG) inhibition at 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(Nc1nnc(SCc2ccc(F)cc2)s1)c1ccc2c(c1)C(=O)N(c1ccccc1Cl)C2=O
[b] CCN=C1SC(C(=O)Nc2ccc(Cl)c(Cl)c2)CC(=O)N1CC
[c] O=S(=O)(Cc1ccccc1)NCc1cccnc1
[d] Cn1c(C(=O)NN)cc2cc(Oc3ccccc3)ccc21
[e] O=S(=O)(NCCc1csc(-c2ccccc2)n1)c1ccc2c(c1)OCCO2
Answer: a. O=C(Nc1nnc(SCc2ccc(F)cc2)s1)c1ccc2c(c1)C(=O)N(c1ccccc1Cl)C2=O
