Which Scion concept first previewed the production Toyota C-HR?

The Scion C-HR Concept was the first concept to preview the production Toyota C-HR.

Toyota developed the C-HR as a compact crossover with an aggressively styled, coupe-like profile. Before the production model appeared, the design was shown under the Scion name, reflecting Toyota’s plan at the time to use its youth-oriented North American marque for the vehicle.

The Scion C-HR Concept was followed by the Toyota C-HR Concept, bringing the design closer to the form that would reach production. Toyota presented the production C-HR at the March 2016 Geneva Motor Show, and production began later that year.

The other choices are unrelated Scion concepts. The t2B, Hako and Fuse each explored different small-car or design themes, but they were not the concept that directly previewed the C-HR. Another source of confusion is that the production vehicle ultimately launched as a Toyota after Scion was discontinued.
