For the design of component measuring 1000 mm by 500 mm, the dimensions would normally be entered at a scale of? (a) 1:1 (b) 1:2 (c) 1:5 (d) 1:10

Thanks for the invite the answer scale 1:2 

Drawing scale 1: 2 (one for two) means that the thing is twice as big as the drawing

I guess Option B -------------------

My opinion Option D is the right choice. 

Thanks for the invite. Sorry, the question is out of my field.

Thanks for Invitation

Option B
