If the tryparse method determines that the string cannot be converted to the data type, it assigns . . . . . . . . to the variable.

The correct answer is: C. 0

The TryParse method returns a value of type bool indicating whether the conversion was successful. If the conversion was successful, the value of the variable is assigned the converted value. If the conversion was not successful, the value of the variable is assigned 0.

Option A: -1 is not a valid return value for the TryParse method.
Option B: 1 is not a valid return value for the TryParse method.
Option D: 2 is not a valid return value for the TryParse method.
