Solution
The correct option is C Both A and B
• Campylotropous ovule- This type of ovule is similar to Anatropous ovule but the curvature is less than that of an anatropous ovule. Micropyle is near to the funiculus. Chalaza and micropyle lie in the straight line but hilum is at 90° to the micropyle.• Amphitropous ovule- The body of ovule gets curved along with the embryo sac in such a way that it becomes horseshoe-shaped.
• Hemianatropous ovule- The body of ovule is turned through 90° and micropyle and chalaza lie in a straight line but funiculus is at a right angle or 90° with both these two.
Hence, it is in Campylotropous and Amphitropous ovule in which Hilum, chalaza, and micropyle come to lie nearby. So, the correct answer is C.
