B Correct answer
Explanation

Let Ram's income be 4x and Shyam's income be 5x. Since Ram saves 1/4 of his income, his expenditure is 3/4 × 4x = 3x, so his savings is 4x - 3x = x. The expenditure ratio is 3:4, so Shyam's expenditure is 4/3 × 3x = 4x, making his savings 5x - 4x = x. Therefore, the ratio of their savings is x:x = 1:1.
