Wait, the options: a) Fabaceae (legumes), b) Solanaceae (nightshades), c) Poaceae (grasses, which include corn, wheat, rice), d) Rosaceae (roses, fruits like apples). So the correct answer is c) Poaceae.

Plant root system's primary functions: a) Photosynthesis is in leaves. b) Roots anchor the plant and absorb water/nutrients. c) Attracting pollinators is flowers. d) Transporting sugars is phloem (in stems/leaves). So correct is b.

Hierarchical classification (taxonomy) levels: Kingdom (broadest) → Phylum → Class → Order → Family → Genus → Species (most specific). So Species is the most specific. Option d.
