Explanation

$\textbf{Correct option: }$ B

$\textbf{ Solution: }$

$\textbf{ Option (a): }$

$\bullet$ A multicellular organism contains more than one cell.

$\bullet$ This type of organism contain various types of cells which perform different functions.

$\textbf{ Option (b): }$

$\bullet$ The unicellular organism are the single celled organism.

$\bullet$ This single celled organism is responsible for performing all function of the organism metabolism.

$\textbf{ Option (c): }$

Acellular organism are not made up of cells or divided into cells.

Different cells have different sizes. Arrange the following cells in ascending order of their size and select the correct option:

(i) Mycoplasma (ii) Ostrich egg
(iii) Human RBCs (iv) Bacteria

0%
(i) $\rightarrow$ (iv) $\rightarrow$ (iii) $\rightarrow$ (ii)
0%
(i) $\rightarrow$ (iii) $\rightarrow$ (iv) $\rightarrow$ (ii)
0%
(ii) $\rightarrow$ (i) $\rightarrow$ (iii) $\rightarrow$ (iv)
0%
(ii) $\rightarrow$ (ii) $\rightarrow$ (i) $\rightarrow$ (iv)

Explanation

The smallest cell is Mycoplasma (0.1-0.5 $\mu m$ ).
The bacterial cell measures 3-5 $\mu m$ in length.
Erythrocytes (RBCs) are 6-8 $\mu m$ in diameter.
The largest cell is the egg of an ostrich.

So, the correct answer is option "(i)

$\rightarrow$ (iv)

$\rightarrow$ (iii)

$\rightarrow$ (ii)".
