Final answer:
The coal falls into the water after the straw bridge collapses under its weight. Option 4 is correct
Step-by-step explanation:
In the fable "The Straw, the Coal, and the Bean," the coal's precarious journey across the straw bridge ends abruptly as the bridge collapses. Unable to sustain the coal's weight and overcome by the fear of the rushing water below, the straw gives way, leading to the coal's demise.
Consequently, the correct answer to what happens next is that the straw collapsed and the coal fell into the water. This unfortunate event emphasizes the fable's underlying message regarding the unpredictability of life and the importance of prudence and caution.
