• Grain Storage Silo Classifications (Deep vs. Shallow Bins):
• Statement (I): In a deep bin, plane of rupture strikes the opposite side of structure before it meets the grain surface. $\implies$ True.
• In deep grain bins, the internal plane of rupture of the granular mass intersects the opposite vertical wall before reaching the top free surface of the grain.
• Statement (II): A grain bin can be classified as deep bin when the depth of grain is greater than the equivalent diameter. $\implies$ True.
• By Janssen and Airy criteria, a bin is classified as a deep bin when grain depth $H \gt D \tan(45^\circ + \phi/2) \approx D$.
• Conclusion: Both Statement (I) and Statement (II) are true (Option 1).

Correct option: (1) Both Statement (I) and Statement (II) are true.
