Answer:
The answer is "Option a, and c".
Explanation:
Following are the description of the Digital Signature choices:
- To change the physical transportation of paper or link files in the computerized messaging system, some processes should be identified and utilized in digital signatures, which enables documentation to be validated unforgivably.
- Using public-key cryptography, digital signatures, that's an exquisite system, that's why options a and b are correct.
- Digital signatures are not a central authority, that's why the option B is wrong.

Answer:
The program in Python is as follows:
num1 = int(input())
num2 = int(input())
if num1 >=0 and num2 >= 0:
print(num1+num2)
elif num1 <0 and num2 < 0:
print(num1*num2)
else:
if num1>=0:
print(num1**2)
else:
print(num2**2)
Explanation:
This gets input for both numbers
num1 = int(input())
num2 = int(input())
If both are positive, the sum is calculated and printed
<em>if num1 >=0 and num2 >= 0:</em>
<em> print(num1+num2)</em>
If both are negative, the products is calculated and printed
<em>elif num1 <0 and num2 < 0:</em>
<em> print(num1*num2)</em>
If only one of them is positive
else:
Calculate and print the square of num1 if positive
<em> if num1>=0:</em>
<em> print(num1**2)</em>
Calculate and print the square of num2 if positive
<em> else:</em>
<em> print(num2**2)</em>
