Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The phrase is 'spend time (in) doing something'. After 'spend', we can use the structure 'spend time in + -ing form' where 'in' can sometimes be omitted. 'Sight seeing' should be 'sightseeing' (one word), but grammatically D is the intended answer showing the 'in + -ing' structure.
