The correct option is A Leaves of Ilex
Botanical name of paraguay tee is Ilex paraguayensis.
This large, white-flowered shrub grows wild near streams, but is largely cultivated in South America for the drink obtained by infusing the leaves. The leaves are alternate, large, oval or lanceolate and broadly toothed. The fruit is a red drupe the size of pepper grains. Its name of 'yerba' signifies the herb par excellence, and the consumption in South America is vast, as it is drunk at every meal and hour. 'Mat' is derived from the name of the vessel in which it is infused in the manner of tea, burnt sugar or lemon-juice being added. It is sucked through a tube, usually of silver, with a bulb strainer at the end and the cup is passed round.
If the powder is dropped into water and stirred the mixture it is called as 'cha mat'.
