Poplar ETPs are:
C. Whole one-year plants
Entire transplants (ETPs) are whole one-year-old poplar plants with roots and shoots, planted in winter. Unrooted cuttings, tissue culture plantlets and seed pellets are other kinds of stock.

Casuarina fixes nitrogen with:
C. Frankia
Casuarina fixes nitrogen with Frankia actinomycetes in root nodules. Rhizobium nodulates legumes; free-living Azotobacter and mycorrhizal fungi do not form these nodules.

Neem seed should be sown:
B. Fresh
Neem seed loses viability within weeks to a few months, so it is sown fresh. It cannot be stored for years, does not need acid treatment, and freezing would harm it.

Hardwickia binata is raised by direct sowing or tall containers because:
B. An early long tap root
Anjan develops a long tap root early while its shoot grows slowly at first, so it is sown directly or in tall containers. It has roots from the start, its seed is not recalcitrant, and it is not a climber.

Bamboo offsets consist of:
B. A rhizome with a culm base
Bamboo offsets are rhizomes with the base of a culm attached, the traditional planting material for clump-forming bamboos. Seeds, leaves and branch tips are not offsets.
