D Correct answer
Explanation

Reason: In angiosperms, plant embryos in seeds have structures called cotyledons. Cotyledons are called 'seed leaves' because when they emerge during seed germination they become green. Thus, cotyledon represents pre-design plant in the seed. The angiosperms are divided into two groups based on the number of cotyledons present in the seed. (1) Monocotyledonous or monocots - Plants with seeds having single cotyledon, e.g. Paphiopedilum (2) Dicotyledonous or dicots - Plants with seeds having two cotyledons, e.g. Ipomoea.
