Answer:
B) Some time
Step-by-step explanation:
Out of all of the answer options, option B) is correct here. Lets discuss why the other options don't work.
Option A uses the phrase "sometime". Using this spelling, the definition is "at some unspecified or unknown time"
Option C) uses the phrase "sometimes", which is defined as "occasionally, rather than all of the time"
We can use process of elimination to determine that B) is correct.
