Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.043\% 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 other words.
Options:
a.) O=C(NCCc1ccc(Cl)cc1)C1CCCN(c2ncnc3c2nc2n3CCCCC2)C1
b.) COc1ccc(-c2nc3c(c4nnc(SC(C)C(=O)Nc5ccc(C)cc5)n24)COC(C)(C)C3)cc1
c.) Cc1cc(=O)oc2c3c(cc(OCC(=O)NCc4ccccc4)c12)OC(C)(C)CC3
d.) Cc1cc(C)c2sc(NC(=O)c3ccc([N+](=O)[O-])o3)nc2c1
Answer: c. Cc1cc(=O)oc2c3c(cc(OCC(=O)NCc4ccccc4)c12)OC(C)(C)CC3
