A
II to III
B
IV to I
C
I to II
D
III to IV
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
Pollination is the transfer of pollen grains from the male anther of a flower to the female stigma, either within the same flower or to another flower.
From the diagram provided in the question, I - Petal II - anther III -stigma IV - ovule. Hence, the transfer of pollen grain is from II to III.
See diagram above for better understanding.

Solution
The type of joint between adjacent bones in the part labelled II is the
Attached Figure / Diagram
A
hinge joint
B
ball and socket joint
C
suture joint
D
sliding joint
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
The joints between the adjacent processes of the vertebrae (specifically the facet joints or zygapophyseal joints) are classified as sliding joints (also known as gliding or plane joints). These joints consist of flat or nearly flat articular surfaces that allow the bones to slide or glide over one another, providing the flexibility needed for the spine to bend and twist while maintaining stability.
A. hinge joint: These allow movement in only one plane, like a door. While some specialized spinal junctions in certain animals are described as hinge-like, the standard classification for human intervertebral facet joints is sliding/gliding.
B. ball and socket joint: These provide the highest range of motion and are found in the shoulders and hips, where a rounded bone head fits into a cup-like depression.
C. suture joint: These are immovable fibrous joints found only between the bones of the skull.
