(b) Sugar
(c) Glucose
(d) Starch

Options

A. `bltclt dlt a`
B. `clt alt blt d`
C. `alt clt blt d`
D. `blt dlt alt c`

Explanation

To arrange the given compounds in the increasing order of carbon atoms present in them, we will first identify the number of carbon atoms in each compound.

1. **Identify the compounds and their formulas:**
- (a) Methane: CH₄
- (b) Sugar: C₁₂H₂₂O₁₁
- (c) Glucose: C₆H₁₂O₆
- (d) Starch: C₆H₁₀O₅ (Note: Starch is a polysaccharide and can be represented as (C₆H₁₀O₅)ₙ, where n is a large number, indicating multiple glucose units.)

2. **Count the carbon atoms in each compound:**
- **Methane (CH₄)**: Contains 1 carbon atom.
- **Sugar (C₁₂H₂₂O₁₁)**: Contains 12 carbon atoms.
- **Glucose (C₆H₁₂O₆)**: Contains 6 carbon atoms.
- **Starch (C₆H₁₀O₅)**: Contains 6n carbon atoms (where n is the number of glucose units, and n is typically greater than or equal to 1).

3. **List the number of carbon atoms:**
- Methane: 1 carbon atom
- Glucose: 6 carbon atoms
- Starch: 6n carbon atoms (n ≥ 1, so at least 6 carbon atoms)
- Sugar: 12 carbon atoms

4. **Arrange the compounds in increasing order of carbon atoms:**
- The order based on the number of carbon atoms is:
1. Methane (1 carbon)
2. Glucose (6 carbon)
3. Starch (6n carbon, where n is at least 1, so it is equal to or greater than 6)
4. Sugar (12 carbon)

5. **Final arrangement:**
- The increasing order of carbon atoms is:
- (a) Methane < (c) Glucose < (d) Starch < (b) Sugar

Thus, the correct order is **A, C, D, B**.
