Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.745\% 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 additional words.
Options:
[a] Cc1ccc(-c2noc(CNC(=O)COc3ccccc3C)n2)cc1
[b] NCc1ccccc1COc1ccccc1.O=C(O)/C=C\C(=O)O
[c] COc1ccccc1OCCNC(=O)c1ccc(Br)cc1
[d] Cc1cc(Nc2ccc(C(C)C)cc2)n2ncnc2n1
Answer: b. NCc1ccccc1COc1ccccc1.O=C(O)/C=C\C(=O)O
