Question $8(1$ point$)$

Rosa and Elliot are discussing a new marketing campaign they are developing for United Airlines. Elliot suggests they should mix up the messaging, being funny in some ads and serious in others; using celebrity endorsers for some elements but everyday people $($i$.$e$.,$ non$-$celebrities$)$ for others. Rosa saw some value in Elliot's approach, but she reminded him that a key idea of Integrated Marketing Communication is what?

Marketing campaign elements should be consistent in look, feel, and tone

Marketing campaign elements should be as diverse and unique from each other as possible

Marketing campaign elements should change all the time so that no one ever sees the same ad$,$ commercial, or billboard twice

Marketing campaign elements should only use different emotions

Marketing campaign elements should never include "everyday people"
