I believe the correct answer is the second option. Monocots and dicots are two groups of angiosperms. This group of plants are seed bearing plants. Flowers are their reproductive system where the ovules are being enclosed in the ovary. Angiosperms can be found in every habitat from grasslands and forests to deserts and sea margins. Angiospersms are divided to monocots and dicots. Monocot plants are characterized by having one cotyledon while dicots have two. Also, leaf veins of monocots are branched while that of dicots are parallel. The root system of monocots is a fibrous root system while dicots have a taproot system.
