Matplotlib - Animations

ABy updating the y-values of the sine wave for each frame and redrawing the plot

BBy plotting all sine waves at once and hiding them one by one

CBy saving each sine wave as a separate image without updating the plot

DBy changing the plot title only without changing data

Step-by-Step Solution

Solution:

Step 1: Understand animation data update
To show change, the data points (y-values) must update each frame to reflect the sine wave moving.
Step 2: Identify correct animation method
Updating y-values and redrawing the plot each frame creates the visual change over time.
Final Answer:
By updating the y-values of the sine wave for each frame and redrawing the plot -> Option A
Quick Check:
Data update per frame = animation change [OK]

Quick Trick: Change data points each frame to animate [OK]
