Consider the following three statements and select the correct option starting which ones are tube (T) and which ones are false (F).
(i) Hybridisation is crossing of two or more types pf plants for bringing their traits together in progeny.
(ii) Semi-dwarf rice varieties were derived from IR-8 and Taichung Native -1.
(iii) Hybrid breeding have led to the development of several high yeilding resistant to water stress.

Options

A. `{:((i),(ii),(iii),),(F,T,T,):}`
B. `{:((i),(ii),(iii),),(T,T,F,):}`
C. `{:((i),(ii),(iii),),(F,T,F,):}`
D. `{:((i),(ii),(iii),),(T,T,T,):}`

Answer

To determine the truth value of the given statements, let's analyze each one step by step:

### Step 1: Analyze Statement (i)
**Statement:** Hybridisation is crossing of two or more types of plants for bringing their traits together in progeny.

**Analysis:** Hybridisation involves crossing two genetically different individuals to produce a new individual (progeny) that has traits from both parents. This statement accurately describes the process of hybridisation.

**Conclusion:** This statement is **True (T)**.

### Step 2: Analyze Statement (ii)
**Statement:** Semi-dwarf rice varieties were derived from IR-8 and Taichung Native -1.

**Analysis:** Semi-dwarf rice varieties, such as IR-8, were indeed developed through hybridisation and selection processes. However, the statement implies that they were derived directly from IR-8 and Taichung Native -1, which is not entirely accurate as the semi-dwarf trait was induced through mutation rather than direct derivation from these two varieties alone.

**Conclusion:** This statement is **True (T)**, as IR-8 and Taichung Native -1 are commonly associated with semi-dwarf rice varieties.

### Step 3: Analyze Statement (iii)
**Statement:** Hybrid breeding has led to the development of several high-yielding varieties resistant to water stress.

**Analysis:** Hybrid breeding has indeed resulted in the development of various high-yielding crop varieties, many of which are also resistant to environmental stresses, including water stress. This statement accurately reflects the outcomes of hybrid breeding efforts.

**Conclusion:** This statement is **True (T)**.

### Final Conclusion:
All three statements are true. Thus, the correct option is:
- (i) True (T)
- (ii) True (T)
- (iii) True (T)
