Problem statement: Answer the multiple choice question.
Question: Which drug has a 3.787\% 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. O=[N+]([O-])c1ccc2c3n([n+]([O-])c2c1)CCN=C3c1ccc(Cl)cc1
b. CC(=O)c1ccc(S(=O)(=O)N(C)CC(=O)N2CCCCCC2)cc1
c. O=C(O)CCCC(=O)N1CCN(c2cccc(Cl)c2)CC1
d. COc1ccc(C(=O)NCC(c2ccc(F)cc2)N2CCOCC2)cc1S(=O)(=O)N1CCCC1
Answer: a. O=[N+]([O-])c1ccc2c3n([n+]([O-])c2c1)CCN=C3c1ccc(Cl)cc1
