Option a:
268 * 4 * 8 * 5 * 14 = 41
After replacement of signs,
268 + 4 x 8 - 5 ÷ 14 = 41
268 + 32 - 0.35 = 41
299.65 is not equal to 41
Option b:
268 * 4 * 8 * 5 * 14 = 41
After replacement of signs,
268 x 4 ÷ 8 + 5 - 14 = 41
268 x 0.5 + 5 - 14 = 41
139 - 14 = 41
125 is not equal to 41
Option c:
268 * 4 * 8 * 5 * 14 = 41
After replacement of signs,
268 ÷ 4 x 8 + 5 - 14 = 41
67 x 8 -9 = 41
536 - 9 = 41
527 is not equal to 41
Option d:
268 * 4 * 8 * 5 * 14 = 41
After replacement of signs,
268 ÷ 4 - 8 x 5 + 14 = 41
67 - 40 + 14 = 41
27 + 14 = 41
So, 41 = 41
Thus, Option (d) is the correct answer.
