Match the columns and find correct options
`{:((a),"Saprophytic protists",(i),"Trypanosoma"),((b),"Golden algae",(ii),"Plasmodium"),((c),"Malarial parasite",(iii),"Desmids"),((d),"Sleeping sickness",(iv),"Slime moulds"):}`

Options

A. (a)-(i), (b)-(ii), (c )-(iii), (d)-(iv)
B. (a)-(ii), (b)-(iii), (c )-(iv), (d)-(i)
C. (a)-(iv), (b)-(iii), (c )-(ii), (d)-(i)
D. (a)-(ii), (b)-(iv), (c )-(i), (d)-(iii)

Answer

To solve the matching question, we need to align the items in the first column with the correct items in the second column based on their characteristics. Here’s the step-by-step solution:

### Step 1: Identify the characteristics of each item in the first column.

1. **Saprophytic protists** - These are organisms that feed on dead organic matter.
2. **Golden algae** - These are unicellular algae known for their golden-brown color due to the presence of specific pigments.
3. **Malarial parasite** - This refers to the organism that causes malaria, which is transmitted by mosquitoes.
4. **Sleeping sickness** - This is a disease caused by certain protozoa, transmitted by tsetse flies.

### Step 2: Match each item with the correct organism or group from the second column.

1. **Saprophytic protists** - The correct match is **(iv) Slime molds**. Slime molds are known for their saprophytic nature as they feed on decaying organic matter.

2. **Golden algae** - The correct match is **(iii) Desmids**. Desmids are a group of green algae that are often referred to as golden algae due to their pigmentation.

3. **Malarial parasite** - The correct match is **(ii) Plasmodium**. Plasmodium is the genus of the protozoan that causes malaria.

4. **Sleeping sickness** - The correct match is **(i) Trypanosoma**. Trypanosoma is the protozoan responsible for causing sleeping sickness.

### Step 3: Write down the final matches.

- (a) Saprophytic protists → (iv) Slime molds
- (b) Golden algae → (iii) Desmids
- (c) Malarial parasite → (ii) Plasmodium
- (d) Sleeping sickness → (i) Trypanosoma

### Conclusion:

The correct matches are:
- (a) → (iv)
- (b) → (iii)
- (c) → (ii)
- (d) → (i)

Therefore, the right answer for the question is option number three.
