Option 1: Rice is a monocot seed, not a dicot seed. Monocot seeds have only one cotyledon, while dicot seeds have two cotyledons.
Option 2: Wheat is also a monocot seed, not a dicot seed.
Option 3: Pulses, such as peas and beans, are examples of dicot seeds. They have two cotyledons, making them dicotyledonous.
Option 4: Maize is a monocot seed as well.
Therefore, the correct answer is option 3, Pulses, as it is the only example in the given options that represents a dicot seed.
