Option A is the correct answer.
Option Analysis
The statement says the uniform width of the walkway is 3 feet. Nothing more info on that.
Statement I is sufficient: We know the outer perimeter as 124 ft. So we can find the length and width. And if we subtract the 3 feet (Uniform) from both length and breadth we find the perimeter of the garden- Sufficient.
Statement II is insufficient: we know the area, but we do not know whether the area includes the walkway or not. Also, in either case, we may have multiple values of length and breadth which can give the area of 600 feet. So In-sufficient
