According to the information given, the drop in the velocity of M1 occurred between 2007 and 2017. Therefore, we need to find the difference between the velocity in 2007 and 2017 and express it as a percentage.

Using the formula ((New value - Old value) / Old value) x 100, we get:

((5.5 - 10.5) / 10.5) x 100 = -47.62%

However, the question asks for the "drop" and not the "decrease", so we need to convert the result to a positive percentage:

|-47.62%| = 47.62%

Rounding to one decimal place, we get a drop of almost 50 percent, which is option D.
