1. 48

2. 72

3. 90

4. 120

The correct answer is: 90

The recommended duration for soaking grass seed in warm water for pre-hydration is 90 hours. Soaking the seeds serves several essential purposes. It allows the seeds to absorb water, which can help to initiate the germination process more effectively and efficiently. By hydrating the seeds in advance, it increases the chances of successful growth and establishment once they are sown into the soil. Pre-hydration can also enhance the speed of germination and improve the overall vigor of the grass, leading to a healthier lawn. Ensuring the seeds are adequately soaked within this timeframe can make a difference in achieving optimal results.
