A programmer likes to do certain activities depending on the time of day and the prevailing weather conditions. The code accepts two string variables `weather` and `time` as inputs and prints the corresponding activity as output. Which statements about the code execution are true? The options are independent of each other.
```
weather = input()
time = input()
if weather == 'sunny':
if time == 'morning':
activity = 'read'
else:
activity = 'walk'
if weather == 'rainy':
activity = 'sleep'
if weather == 'cold':
if time == 'morning':
activity = 'read'
else:
activity = 'watch'
print(activity)
```
