Answer:

Option A.

Explanation:

The given ratios are 2:3, 3:4, 5:6, 1:5.

We need to arrange these ratios in descending order.

Fraction form of given ratios are

(2)/(3),(3)/(4),(5)/(6),(1)/(5)

First find LCM of denominators.

LCM(3,4,6,5)=60

Now, make denominator common, i.e., 60.

(2* 20)/(3* 20),(3* 15)/(4* 15),(5* 10)/(6* 10),(1* 12)/(5* 12)

(40)/(60),(45)/(60),(50)/(60),(12)/(50)

Now, arrange numerator in descending order.

50>45>40>12

$\Rightarrow (50)/(60)>(45)/(60)>(40)/(60)>(12)/(50)$

$\Rightarrow (5)/(6)>(3)/(4)>(2)/(3)>(1)/(5)$

$\Rightarrow 5:6>3:4>2:3>1:5$

Therefore, the correct option is A.
