Task: Answer the multiple choice question.
Query: Which drug has a 19.156\% 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 COc1cccc(NC(=O)c2cc(S(=O)(=O)N3CCc4ccccc43)cn2C)c1
b O=C(O)c1cc2ccccc2c(N=Nc2cccnc2)c1O
c Nc1ccc(N2CCOCC2)c(Cl)c1
d CCOc1ccc(S(=O)(=O)Nc2cccc(C(=O)NCCCN3CCCC3=O)c2)cc1
Answer: a. COc1cccc(NC(=O)c2cc(S(=O)(=O)N3CCc4ccccc43)cn2C)c1
