Answer:
Following are the program in the Python Programming Language.
#declare variable and initialize to 0
sum = 0
#read the following file
file = open('numbers.txt', 'r')
#set the for loop
for n in file:
#convert the file string into the integer and perform sum.
sum += int(n)
Explanation:
<u>The following are the description of the program</u>.
- Firstly, declare variable 'sum' and initialize the integer type value i.e., 0.
- Set the variable 'file' that only read the following file text i.e., 'numbers.txt'.
- Set the for loop that read the content of the file and store in the variable 'n' one by one.
- Finally, er convert the following string in to the integer and perform the addition.

Answer:
Option D is the correct answer to the following question.
Explanation:
The following option is correct because three sets type variable i.e., "fruit", "fruit2", "fruit3" has contain the same values in it and then they ask for the option is correct if the all are equal and in the option c, there is the if statement in which check the condition if the variable "fruit" is equal to the variable "fruit2" and the variable "fruit" is equal to the variable "fruit3".
so, that' why the following option is correct.
The option A is not correct because there is no equal function in python and we use the operator == to check the condition.
The option B is incorrect because we can see that there is not equal to (!=) operator.
The option D is incorrect because we can see that there is an or operator are used which means if any of the conditions is true then, they return either the other condition is false.
A time signal will do that, I believe!
In my opinion, XYplorer is the best
