DI - Will be of two types
1. Definite Value - What is value of x?
2. Yes/No - Is X greater than 10? Is X odd etc

Now your answer will be again of two categories
AD OR BCE
If A is not possible D is also out
If A is not possible then immediately only BCE will be out

Divide always the page into 3 segments - draw three lines
For first just solve for A, Then B then combined

Now on solving

Always deconstruct the Q stem - sometimes it may be complicated to comprehend always ease it out and finally understand what you have to find or prove

Then keep those constraints in mind

Now on options A and B

For category 1:
If you get two values - then it is not an ans

For category 2:
First prove the statement such that it guves you a yes answer, then check if you can get a No.
If you can get yes and no both - then it is incorrect.

Issues with data sufficiency definetely also signal concept clarity. So great to check.
