Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -1.745\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] Cc1cc(C)c2ccc(NN)nc2c1O
[b] CCc1ccc(C(=O)NC(CC(C)C)C(=O)O)cc1
[c] Cc1nn(-c2ccccc2)c2c1C(c1ccc([N+](=O)[O-])cc1)C(C#N)=C(N)O2
[d] C/C=C/c1ccc(OCCCNCC(C)O)c(OC)c1
Answer: b. CCc1ccc(C(=O)NC(CC(C)C)C(=O)O)cc1
