Workability of concrete is inversely proportional to a) time of transit b) water/cement ratio c) the air in the mix d) size of aggregate

The answer is   b) water/cement ratio

Option "b " workability of concrete is inversely proportional to water / cement ratio.

I think it is trick question, the trick is "

 

inversely ".

So the answer is 

a) time of transit 

because its the only one if it's increase, the workability of concrete will be decreased.

 

Workability always bese on maximum amount of water, recommended size of aggregate (aqouter Inc) Sand ratio, cement .

 answer B is the most important factor 

but all other factories is also effect the concrete workability
