Explanation

This question appears to be about data normalization, but the context is incomplete as we don't have the original data range or normalization formula. However, based on typical normalization approaches:

• Normalization to [0,1] range is typically done using: $X_{norm} = \frac{X - X_{min}}{X_{max} - X_{min}}$
• Without knowing the minimum and maximum values of the dataset, we cannot definitively calculate the normalized value
• The question likely assumes the reader has access to the full dataset context where the range is provided

Given that option C (0.73) is selected as the answer, it suggests that in the original context, the data range was such that 149 maps to approximately 0.73 when normalized.
