With the help of the given variables, identify the correct sequence, that leads to the formation of blood clot
(A) Blood clot (B) Injury
(C) Factor II (D) Factor III
(E) Factor IV (F) Fibrinogen
(G) Thrombin

Options

A. `B rarr C rarr D rarr F rarr G rarr A`
B. `B rarr underset(D uarr e^(+))(C rarr G)rarr F rarr A`
C. `D rarr underset(uarr e^(+))(B) rarr C rarr G rarr F rarr A`
D. `B rarr underset(uarr e^(+))(D rarr ) C rarr F rarr G rarr A`

Explanation

To identify the correct sequence that leads to the formation of a blood clot, we can follow these steps based on the provided variables:

1. **Injury (B)**: The process begins with an injury to a blood vessel, which triggers the clotting mechanism.

2. **Factor III (D)**: Following the injury, Factor III (also known as thromboplastin) is released, which is essential for the conversion of prothrombin to thrombin.

3. **Factor II (C)**: This refers to prothrombin, which is a precursor to thrombin. It is activated in the presence of Factor III and calcium ions.

4. **Thrombin (G)**: Factor II (prothrombin) is converted into thrombin (G) by the action of Factor III and calcium ions.

5. **Fibrinogen (F)**: Thrombin then acts on fibrinogen, converting it into fibrin.

6. **Blood Clot (A)**: Finally, the fibrin forms a mesh-like structure that traps blood cells and platelets, leading to the formation of a blood clot.

Thus, the correct sequence is:
B → D → C → G → F → A
