Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.691\% 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, or d without using any additional words.
Options:
[a] S=C(NNc1ccnc2cc(Cl)ccc12)Nc1ccc(Cl)cc1Cl
[b] CC(C)(C)C(=O)Nc1cccc(OC(F)(F)C(F)Cl)c1
[c] C/C(CC(=O)Nc1cc(C)ccn1)=N\NC(=O)c1ccccc1C
[d] CNC(=O)c1c(NC(=O)c2ccc(S(=O)(=O)N(C)c3ccccc3)cc2)sc2c1CCN(C(C)C)C2
Answer: a. S=C(NNc1ccnc2cc(Cl)ccc12)Nc1ccc(Cl)cc1Cl
