Read the given statements each with one or two blanks. Select the option that correctly fills the blanks in any two statements.
(a) ___(i)____ is the process of aerobic burning whereas ___(ii)____ is anaerobic burning of combustible constituent of solid waste at high temperature.
(b) ___(i)___ secretes mucus and watery alkaline fluid that contains fructose.
(c) Tendrils of Cucurbita and thorns of Bougainvillea are ___(i)___ organs while wings of birds and insects are ____(ii)____ organs.
(d) Rate of heart beat and breathing movements of human body are controlled by ___(i)____

Options

A. (b) - (i) - Seminal vesicles,
(c) - (i) - Analogous, (ii) - Homologous
B. (c) - (i) - Homologous, (ii) - Analogous,
(d) - (i) - Medulla oblongata
C. (a) - (i) - Pyrolysis, (ii) - Incineration,
(b) - (i) - Cowper's gland
D. (a) - (i) - Incineration, (ii) Pyrolysis,
(d) - (i) - Diencephalon

Answer

To solve the question, we need to fill in the blanks for any two of the given statements correctly. Let's analyze each statement step by step.

### Step-by-Step Solution:

**Statement (a)**:
1. The first part of statement (a) refers to the process of aerobic burning. The correct term for this process is **incineration**.
2. The second part refers to the anaerobic burning of combustible constituents of solid waste at high temperatures. The correct term for this process is **pyrolysis**.
3. Thus, the completed statement (a) is: **(i) incineration is the process of aerobic burning whereas (ii) pyrolysis is anaerobic burning of combustible constituent of solid waste at high temperature.**

**Statement (b)**:
1. This statement mentions a structure that secretes mucus and a watery alkaline fluid containing fructose. This is related to the male reproductive system.
2. The correct answer for this structure is **seminal vesicle**.
3. Thus, the completed statement (b) is: **(i) seminal vesicle secretes mucus and watery alkaline fluid that contains fructose.**

**Statement (c)**:
1. Tendrils of Cucurbita and thorns of Bougainvillea are both types of modified plant organs. They are considered **homologous organs** because they have a similar origin but different functions.
2. Wings of birds and insects are considered **analogous organs** because they have similar functions (flight) but different anatomical structures.
3. Thus, the completed statement (c) is: **(i) homologous organs while (ii) analogous organs.**

**Statement (d)**:
1. The rate of heartbeat and breathing movements of the human body are controlled by a specific part of the brain.
2. The correct answer is **medulla oblongata**.
3. Thus, the completed statement (d) is: **(i) medulla oblongata.**

### Final Answers:
- For statement (a): **(i) incineration, (ii) pyrolysis**
- For statement (b): **(i) seminal vesicle**
- For statement (c): **(i) homologous, (ii) analogous**
- For statement (d): **(i) medulla oblongata**

### Selected Options:
The correct options that fill the blanks in any two statements are:
- **(a)**: incineration, pyrolysis
- **(b)**: seminal vesicle
