Answer:
Option b. The value is a floating-point number that should be displayed with 2 decimal places.
Explanation:
The f is a format code for a floating point number. Sometimes, a specific precision is required to display a floating point number. To meet the precision requirement, we can precede the f with a dot and followed with a precision value.
For example:
print("My value: {0:.2f}".format(123.45678))
will display 123.46
*The output has been rounded up to two decimal places.
