Answer 2

For this case, we can use the data type Tuple.

Explanation:

• Similar to the list, a tuple can also deposit a sequence of elements but the value of the elements can’t be modified.  

• From this, it is meant that tuples are immutable.  

• Elements of the sequence can be heterogeneous or homogeneous but they are read-only.

• For this case, the tuple will be written as:

• $Lunchmenu=("WelcomeDrink","VegStarter","Non-VegStarter",\\"VegMainCourse","Non-VegMainCourse","Dessert")$

• If someone tries to modify the tuple with a random write such as Lunch menu[0]=“”, it will result in an error.
