Information concerning trademarks is available from the Canadian Intellectual Property Office. Kimberley has created a buckwheat product that makes bubbling sounds when liquids are mixed with it. She wants to know if she can secure a trademark for a tune to accompany the words "Bubble,Bubble, here comes buckwheat trouble" to protect the brand she's creating for the "Bubbling Buck" cereal. Based on information provided by the Canadian Intellecftual Property Office, you can advise Kimberley:

a.For sound and moving image trademarks, a description of the trademark is all that is required.

b.Once a trademark is registered, the Trademarks Office will police and prevent others from infringing the mark.

c.Registering a trademark can stop others from using a confusingly similar tune.

d.That the trademark will last only for eight years.
