Choice "a" is incorrect. The auditor should consider whether the year-end balances of the particular asset or liability accounts that might be selected for interim examination are reasonably predictable with respect to amount, relative significance, and composition. Inventory is relatively predictable with respect to amount, composition and relative significance.
Choice "c" is incorrect. During planning, the auditor is required to obtain an understanding of the entity and its environment, including its internal control, and to assess risk. Such preliminary planning is often conducted prior to the balance sheet date.
