CFAI 08 Mock 1 #41

Anyone did this exam? It says: Belle Cuisine exploits the special needs of a niche market, i.e., high quality food for clients at private hospitals, by differentiating through branded quality products. This is differentiation focus or differentiation? Thanks.

might not be in this year’s LOS, sounds unfamliar to me

It’s actually level 1 material that appear in the level II mock last year. I thought it was differentiation focus as they focus on niche market, but the answer got me confused so I want to confirm to see if I was correct.
