Answer:
Option (C) is correct.
Step-by-step explanation:
Given that,
Laboratory research = $270,000
cost of testing prototype = $75,000
construction of research facility = 360,000
The total amount to be classified and expensed as research and development in 2018:
= Laboratory research + cost of testing prototype + construction of research facility
= $270,000 + $75,000 + 360,000
= $705,000
