Statement I is correct because in Unani philosophy, Rukn Hawa (air) is described as lateef (subtle or light) due to its Haar Ratab (hot and moist) temperament.
This nature allows air to penetrate easily and fill spaces, making it subtle and mobile.
Statement II is also correct — Yabusat means dryness, and dryness resists taking and changing shapes easily.
This is a classical characteristic that defines dry matter as firm and rigid in structure, retaining its form.
Therefore, both statements accurately describe the related Unani concepts.
Hence, the correct option is that both Statement I and Statement II are correct.
