Answer:

D. Chain and Sprockets

Explanation:

Chains and sprockets are power transmission tools. The roller chain is connected to a toothed wheel which is the sprocket. The combination provides mechanical power to the wheels of vehicles.

An advantage they possess is their ability to transmit mechanical power over both short and long distances. They have a high degree of efficiency but they require constant lubrication. They also produce noise during operation.

if x < 0:#defining if that checks x less than 0

   print("This number ",  x, " is negative.")#print value with the message

else:#defining else block

   print("This number ",  x, " is negative.")

elif (x > 0):#defining elif block that check x value greater than 0

   print(x, " is positive")#print value with message

else:#defining else block

   print(x, " is 0")#print value with message

Output:

Please find the attachment file.

Explanation:

In this code, an x variable is defined which holds a value that is "0", in the next step nested conditional statement has used that checks the x variable value and uses the print method that compares the value and prints its value with the message.

In another conditional statement, it uses if that checks x value less than 0 and print value with the negative message.

In the elif block, it checks x value that is greater than 0 and prints the value with the positive message, and in the else block it will print the message that is 0.
