''____'' dimension is the largest vertical measurement.

• A. A dimension
• B. B dimension
• C. Frame height
• D. Lens height

Answer: (B)

In eyewear sizing, A is the horizontal width of each lens, while B is the vertical dimension of the lens. The question asks which vertical measurement is the largest, and B is the one that represents the lens height—the vertical span across the lens area. That vertical span is typically the most substantial vertical measurement among common frame dimensions, making it the largest vertical metric in these options. Frame height and lens height describe vertical aspects too, but the B dimension specifically captures the full vertical extent of the lens, which is what’s being compared here.
