A and B provide very little information therefore I would chose C or D. If you look at D it has “Tea Spoons” were that would be right if the question was different. You see your question says “All the Units” UNITS so D cant be correct. This means the answer ost probably should be C.
Question 2:
Same as the last one this has units so I would go for C because it is te most accurate way of time periods.
Question 3:
This could get you off guard because it says “could NOT be used to convert” in short that is referring to the false answer and it seems like the answer here would be D.
Question 4:
Now this question asks that which relation is going to be first. So if you want to make it easier which they are asking you to do I would go for C.
