This type of plastid contains orange pigment.
leucoplasts
chloroplasts
chromoplasts
chlorophyll

The correct answer would be chromoplasts.

Chromoplasts are the type of plastids which contain orange, yellow, or red pigments.

The orange pigment is developed due to the production of carotene while yellow pigment is developed due to the production of xanthophylls.

In contrast, chloroplasts are photosynthetic plastids which contain green colored chlorophyll.

Leucoplasts are usually non-pigmented plastids.
