Let's break down each option and convert the numbers into the same format to determine the correct order from least to greatest.

Option A: 27%, 2.75, √2, 2%

• 27% = 0.27
• 2.75 remains as is.
• √2 ≈ 1.414
• 2% = 0.02

Order: 0.02, 0.27, 1.414, 2.75 → Least to Greatest: 2%, 27%, √2, 2.75

Option B: 27%, √2, 2.75, 26

• 27% = 0.27
• √2 ≈ 1.414
• 2.75 remains as is.
• 26 remains as is.

Order: 0.27, 1.414, 2.75, 26 → Least to Greatest: 27%, √2, 2.75, 26

Option C: √2, 27, 2.75, 27%

• √2 ≈ 1.414
• 27 remains as is.
• 2.75 remains as is.
• 27% = 0.27

Order: 0.27, 1.414, 2.75, 27 → Least to Greatest: 27%, √2, 2.75, 27

Option D: 27, 2.75, √2, 27%

• 27 remains as is.
• 2.75 remains as is.
• √2 ≈ 1.414
• 27% = 0.27

Order: 0.27, 1.414, 2.75, 27 → Least to Greatest: 27%, √2, 2.75, 27

Conclusion:

The correct order from least to greatest is found in Option C: √2, 27, 2.75, 27%.
