1 LITER WATER =1 KG
OR 1000 ML WATER = 1 KG[GIVEN D=1000 KG/ m3d =1000 KG/ m3]
MOLES OF WATER PRESENT IN 1000 ML = 100018000 ML = 100018= 55.55= 55.55
HENCE MOLARITY OF WATER=55.55M=55.55M
HENCE a IS THE CORRECT ANSWER

The density is given to be 1000kg in 1m3 or we can say it is 1000kg in 1000L.
Simplest ratio is 1kg or 1000g in 1L
Molar mass of water is 18 g/mol
Molarity = no. of moles od solute/ volume of solution in litres.
No of moles is given mass by molar mass.
In this case it is 1000/18 mol = 55.555
Therefore molarity is 55.5555/1 (we took volume as 1 L)which is 55.555M
Hope it helps
