The correct choice is D, which is ReDim Preserve strEmployees(65). This option will resize the strEmployees array while preserving the data in elements 0 through 50. The Preserve keyword ensures that existing data is not lost when the array is resized. Option A (ReDim Retain strEmployees(65)) and Option B (ReDim Reserve strEmployees(65)) are not valid syntax in VB.NET. Option C (ReDim Restore strEmployees(65)) is also not valid and does not retain the data in the original array.
