metalic
Explanation:
Atoms having a valence of electron of 1 or 2 are metals. They belong to the first and second group on the periodic table.
In metallic bonds, atoms of metals and alloys joins together.
- The formation of this type of bond is favored by the low ionization energy and a large number of electrons in the valence shells.
- The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
- Most physical properties of metals can be accounted for by this type of bonding.

<h2>c.is the correct option</h2>
Explanation:
Fungi might assist in seed germination by providing the embryos with some of the organic nutrients the fungi have absorbed
- Fungi is an eukaryote which digests food externally and absorbs nutrients directly through its cell walls
- Fungi absorb nutrients through following three ways:
- By decomposing dead organic matter: obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds
- By feeding on living hosts:fungi live in or on other organisms and get their nutrients from their host
- Living mutualistically with other organisms: mutualistic fungi live harmlessly with other living organisms;fungal component absorb water and minerals and provide them to algal component which uses them to make food
In dark,moist environment nutrient availability is less hence fungi helps in providing orchid seeds the nutrients which it has absorbed
