The best farm tool for transplanting of seedling is

Transplanting seedlings requires a tool that can dig a small, precise hole, gently lift the seedling with its root ball intact, and place it carefully into the new position. A hand trowel is ideally suited for this task because of its small, scoop-shaped blade that allows controlled digging at the shallow depths seedlings need.

A shovel is too large and heavy for delicate seedling work; it would disturb the surrounding soil excessively and risks damaging fragile roots. A hand fork is designed for loosening and aerating soil or lifting weeds, not for digging planting holes. A go-to-hell (a flat-bladed, long-handled weeding tool used in West African agriculture) is meant for scraping weeds from the soil surface and is far too aggressive for seedling transplanting.

Examination tip: When questions ask for the "best" tool for a specific farm operation, match the tool's size and blade shape to the precision and depth the task requires.
