Not A - Internet is packet-switched, not circuit-switched. The packets might follow different paths.
Not B - The routers communicate with each other to determine the path.
C correct - The Internet Protocol or IP used by routers to send packets makes no guarantee that they will be delivered. It uses best-effort delivery.
Not D - See answer B above.

Explanation:
One group of students did an experiment to study the movement of ocean water. The steps of the experiment are listed below.
Fill a rectangular baking glass dish with water.
Place a plastic bag with ice in the water near the left edge of the dish.
Place a lighted lamp near the left edge of the dish so that its light falls directly on the plastic bag.
Put a few drops of ink in the water.
The student did not observe any circulation of ink in the water as expected because the experiment had a flaw. Which of these statements best describes the flaw in the experiment? (2 points)
Not enough ink was added.
Not enough water was taken.
The dish was too small for the experiment.
The lamp and the ice bag were at the same place.
Answer:
Answer explained below. Python language used
Explanation:
The size of the square is of size 10. So assuming zero indexing,
vertical side1 (column Index = 5): row index from 5 to 14
vertical side1 (column Index = 14): row index from 5 to 14
horizontal side1 (row Index = 5): column index from 5 to 14
horizontal side2 (row Index = 14): column index from 5 to 14
Note:
while indexing, data_new[a:b,c] denotes,
row index: a to b-1
column index: c
Similarly data_new[a,b:c] denotes,
row index: a
column index: b to c-1
<u>Code:
</u>
import matplotlib.pyplot as plt
import numpy as np
size_1 = 20
size_2 = 20
data_new = np.random.random((size_1,size_2))
data_new[5:15,5] = 4
data_new[5:15,14] = 4
data_new[5,5:15] = 4
data_new[14,5:15] = 4
fig = plt.figure(figsize=(10,10))
plt.imshow(data_new)
plt.colorbar()
plt.show()
