You are a database developer. You plan to design a database solution by using SQL Server
2008. The database will contain a table to stage data from an external source. The imported
data will contain a field named TransactionTime. The TransactionTime field will use the
hh:mm:ss.[nnn] format (such as 12:55:30.123). You need to select the appropriate data type
for the TransactionTime field. You need to achieve this goal by incurring the minimum
amount of storage cost. Which data type should you use?

A.
time

B.
datetime2

C.
smalldatetime

D.
time (1)
