Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 1.914\% 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 other words.
Options:
a. O=[N+]([O-])c1nn(-c2ccc(Cl)cc2)n(O)c1=NCc1ccncc1
b. c1cc(CSc2nnc(-c3ccc4c(c3)OCO4)o2)ccn1
c. Cc1ccccc1C1C2=C(Nc3[nH]n(-c4ccccc4)c(=O)c31)c1ccccc1C2=O
d. CCCCCCCCCCOC(=O)Cn1c(COc2ccc(Cl)cc2)[n+](C)c2ccccc21.[Cl-]
Answer: c. Cc1ccccc1C1C2=C(Nc3[nH]n(-c4ccccc4)c(=O)c31)c1ccccc1C2=O
