Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.261\% 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. CCCCCC(=O)Nc1cccc(C2=NOC3(C2)C[C@@H](C(N)=O)N(C(=O)C2(C)CC2)C3)c1
b. O=C(CSc1nnc(CNC(=O)c2c(F)cccc2F)o1)NCc1ccccc1
c. CCOC(=O)Nc1ccc2c(c1)N(C(=O)N1CCN(C)CC1)c1ccccc1CC2.Cl
d. CCOc1ccc(-n2c(O)c(N=Nc3ccc([N+](=O)[O-])cc3)c(=O)[nH]c2=O)cc1
Answer: c. CCOC(=O)Nc1ccc2c(c1)N(C(=O)N1CCN(C)CC1)c1ccccc1CC2.Cl
