Which lock hints should I use (T-SQL)

BEGIN TRAN A

SELECT id
FROM Inventory
WITH (???)
WHERE material_id = 25 AND quantity > 10

/*
Process some things using the inventory record and
eventually write some updates that are dependent on the fact that
that specific inventory record had sufficient quantity (greater than 10).
*/

COMMIT TRAN A

SELECT id
FROM Inventory (UPDLOCK)
WHERE material_id = 25 AND quantity > 10;
