The correct answer is option 'D' - Grasshoppers.

Heterogametic condition refers to the sex determination system in which one sex has two different types of sex chromosomes. In XY type of male heterogametic condition, males have one X and one Y chromosome, while females have two X chromosomes.

Here is a detailed explanation of why grasshoppers do not show XY type of male heterogametic condition:

1. Drosophila (fruit flies):
- Drosophila is a well-known model organism used in genetic studies.
- In Drosophila, sex is determined by the ratio of X chromosomes to sets of autosomes (non-sex chromosomes).
- Males have one X chromosome and females have two X chromosomes.
- Therefore, Drosophila shows XY type of male heterogametic condition.

2. Human beings:
- In humans, sex is determined by the presence of sex chromosomes.
- Males have one X and one Y chromosome (XY), while females have two X chromosomes (XX).
- Therefore, human beings show XY type of male heterogametic condition.

3. Elephants:
- Elephants have a different sex determination system compared to most mammals.
- Female elephants have two X chromosomes (XX), while male elephants have one X and one Y chromosome (XY).
- Therefore, elephants also show XY type of male heterogametic condition.

4. Grasshoppers:
- Grasshoppers have a different sex determination system called X0 type of male heterogametic condition.
- In this system, males have one X chromosome and no Y chromosome (X0), while females have two X chromosomes (XX).
- Therefore, grasshoppers do not show XY type of male heterogametic condition.

In summary, out of the given options, grasshoppers do not show XY type of male heterogametic condition. Instead, they exhibit X0 type of male heterogametic condition, where males have one X chromosome and no Y chromosome.
