Gloria, Scott, and Becky are all moving water into a large barrel. Gloria has moved 12 less than 4 times the number of gallons of water as Scott. Becky has moved 16 less than 6 times the number of gallons of water as Scott. If Gloria and Becky have both moved the same number of gallons of water, how many gallons, g, of water has Scott moved?

Which equation below correctly represents the situation above?
A. 4g - 16 = 6g - 12
B. 4g - 6g - 12 = 16
C. 4 × 6 - 12 × 16 = g
D. 4g - 12 = 6g - 16
