B. Price promotion

Answer:
4.53% 
Explanation:
Data provided in the question:
Expected return = ∑ (Return × probability)
Thus,
Expected return = (0.06 × 22) + (0.92 × 13) + (0.02 × (-15))
= 12.98%
Now,
Probability       Return        Probability × (Return-Expected Return)²
0.06                  22                   0.06 × (22% - 12.98%)² = 4.8816
0.92                  13                    0.92 × (13% - 12.98%)² = 0.000368
0.02                  -15                   0.02 × (-15% - 12.98%)² = 5.657608
========================================================
                                                                             Total = 20.5396%
Standard deviation = 
= √(20.5396)
= 4.53%
