It has not been fixed and how is the answer D when all the numbers are right to the 0 and choice B is further to the right than choice A.

If you observe the image, a,b,c,d are all greater than zero

Now there is no specification about a,b,c,d being Integers or fraction but we have following information

0<a<b<c<d

we have to compare axc and bxd

Assuming axc = Z

Now we know that b is greater than a and d is greater than c

So any value of b will be greater than a and any value of d will be greater than c

So if axc = Z then bxd will always be greater than Z.

You can try doing this assuming values as well. but based on the above calculation, axc = Z < bxd

Hope it helps.

Regards,
Mudit
