For near visual acuity, 2M is twice as big as which notation?

Explanation:
Near visual acuity uses M notation to denote letter size relative to a 1-meter reference. The number before M indicates how large the letters are; larger numbers mean larger print. Because the sizes scale with the M value, doubling the M value doubles the letter height. So 2M letters are twice as tall as 1M letters, making 2M twice as big as 1M. The other options would correspond to letters that are smaller (0.5M) or larger (3M) than 2M, not the exact half-size relationship described.
