Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 23.320% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C1OC(c2ccc(Cl)cc2)=C/C1=C/c1cccnc1
b: O=C(NC1CCCc2ccccc21)c1ccc(CNc2c(N3CCOCC3)c(=O)c2=O)cc1
c: O=[N+]([O-])c1cc(Cl)ccc1NCCc1ccccn1
d: O=C(CSc1nc2ccccc2c(=O)[nH]1)NCc1ccc(Cl)cc1
Answer: a. O=C1OC(c2ccc(Cl)cc2)=C/C1=C/c1cccnc1
