Options

C. Either (i) or (iv)
D. Both (iii) and (iv)

Answer

D

Explanation

According to the given information:
Aarti `gt` Sanya ….(i)
Kashish `gt` Muskan `gt` Aarti ….(ii)
Kashish `gt` Sanya .....(iii)
Muskan `gt` Sanya ......(iv)
Gargi `rArr` eldest ....(v)
Combining (i), (ii), (iii), (iv) & (v), we get an arrangement according to descending order of the age.

From (i) & (ii), we get
Kashish `gt` Muskan `gt` Aarti `gt` Sanya.
So, Kashish `gt` Sanya and Muskan `gt` Sanya
So, Both (iii) & (iv) are not needed to answer the above questions.
We used only (i), (ii) & (v) to answer the above question.
Therefore, both (iii) & (iv) are superfluous and can be dispensed.
