Observe the schematic representation of assisted reproductive technology given below:

Identify the most appropriate technique depicted in the above diagram.
Step 1: Understanding ICSI.
- The diagram represents Intracytoplasmic Sperm Injection (ICSI).
- In this technique, a single sperm is directly injected into the cytoplasm of an egg using a fine needle.
Step 2: Use of ICSI. - ICSI is used in cases of male infertility, such as low sperm count or motility.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
