This is a reality question.
Small ruler is about 15 cm. 8 cm is about half of small ruler; so definitely cannot be height of bicycle.
Children’s height (12 years old) is more than 1 m to about 1.4m. The handle of bicycle will be about half to three-quarters of children’s height. So 80 cm is closest match (answer 4).
The height of HDB flat door is about 2m. So 8 m and 80 m definitely out.
Use this reality check if you are asked about height of bus, etc.
