Problem statement: Answer the multiple choice question.
Query: Which drug has a 6.665\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(c1cc(S(=O)(=O)N2CCOCC2)c(Cl)cc1Cl)N1CCCCC1
b.) CCOc1ccc(CCNC(=O)CN(C)S(=O)(=O)c2cccc3nsnc23)cc1OCC
c.) CCC(CC)C(=O)Nc1cccc(SC)c1
Answer: a. O=C(c1cc(S(=O)(=O)N2CCOCC2)c(Cl)cc1Cl)N1CCCCC1
