What is the output of the following program?c = ['code', 'tantra']for t in c:  t.upper()print(c)Options['CODE' , 'TANTRA']TANTRA['code', 'tantra']CODE

The output of the program will be ['code', 'tantra'].

Here's why:

1. The program starts by defining a list c with two strings: 'code' and 'tantra'.
2. Then it enters a for loop where it goes through each element t in the list c.
3. For each element, it applies the upper() method, which converts all the characters in a string to uppercase. However, this doesn't change the original string because strings in Python are immutable, which means they can't be changed after they are created. The upper() method returns a new string and doesn't modify the original one.
4. After the loop, the program prints the list c. Since none of the strings in the list were modified in the loop, the output will be the original list: ['code', 'tantra'].
