C is answer here....
Combining both condition and plugging in value , we can conclude this.
Let range be 'r' cm for A and 's' being range of B.
And highest term of A is 'g' cm ; highest term of B is 'h" cm.
let lowest term of A is 'y' and lowest term of B is 'x'.
So, from 1: r<s>(g-x)
from 2 : g>h .
Now pluging in values we can conclude to get ans yes or no.
But i took almost more than 2 min. to get this...by looking at the first instance.I am just trying to condition myself to test timing....eventhough anybody can get this but might take more time.So,any quicker method !!
