First, we need to convert the height to inches:

4 feet = 48 inches 
11 inches = 11 inches

Total height = 59 inches

Using the formula:

BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) - (4.7 x age in years)

BMR = 655 + (4.35 x 124) + (4.7 x 59) - (4.7 x 33)

BMR = 655 + 539.4 + 277.3 - 155.1

BMR = 1316.6

Rounding to the nearest whole number, we get:

BMR ≈ 1367 calories

Therefore, the answer is D) 1367 calories.
