Answer:
D. The cost of lodging, and incidental expenditures is limited to those incurred during the business portion of the travel.
Step-by-step explanation:
When the travel has both business and personal aspects, the deductibility of the transportation costs depends upon whether business is the primary purpose of a trip. If it is for business the transportation costs are fully deductible, but meals only deductible to 50%.
Lodging and incidental expenditures are limited to those incurred during the business portion of travel.
