Identify the wrong statements
(a) Genetic modifications in plants helped to reduce post-harvest losses
(b) In Tobacco, cry genes are introduced against nematodes
(c) In gene therapy, healthy genes are inserted into person's cells and tissues to treat diseases
(d) Injustice, inadequate compensation and benefit sharing are related to molecular diagnosis.

Options

A. a,b,c
B. b,c,d
C. a,b,d
D. a,c,d

Answer

To identify the wrong statements from the provided options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement (a): Genetic modifications in plants helped to reduce post-harvest losses.**
- This statement is **correct**. Genetic modifications can enhance the shelf life of crops, improve nutritional value, and increase resistance to pests, thereby reducing post-harvest losses.

2. **Statement (b): In Tobacco, cry genes are introduced against nematodes.**
- This statement is **wrong**. In tobacco plants, the RNA interference method is typically used for nematode resistance, not cry genes. Cry genes are primarily used in crops like cotton for pest resistance, not specifically in tobacco against nematodes.

3. **Statement (c): In gene therapy, healthy genes are inserted into a person's cells and tissues to treat diseases.**
- This statement is **correct**. Gene therapy involves inserting healthy genes into a person's cells to replace defective ones, aiming to treat genetic disorders.

4. **Statement (d): Injustice, inadequate compensation, and benefit sharing are related to molecular diagnosis.**
- This statement is **wrong**. The terms "injustice, inadequate compensation, and benefit sharing" are more closely associated with issues of biopiracy and the ethical use of biological resources, rather than molecular diagnosis.

### Conclusion:
The wrong statements are:
- (b) In Tobacco, cry genes are introduced against nematodes.
- (d) Injustice, inadequate compensation, and benefit sharing are related to molecular diagnosis.

### Final Answer:
The wrong statements are (b) and (d).
