A. 0.01 ft
B. 0.1 ft
C. 1 ft
D. 10 ft
E. 100 ft

Answer 1

The global sea-level rise is averaging about 1 foot per century, based on past data and current trends.

Step-by-step explanation:

The rate of global sea-level rise is currently averaging about 1 foot per century. This is based on data indicating that since 1880, sea level has risen by approximately 230 mm, and given the current trend, it is expected that a comparable addition will occur by 2100, resulting in a total of about 0.5 meters (which is roughly equivalent to 1.64 feet, rounded down to 1 foot for the sake of the available options).
