Presence of calcium will remove heparin - blood anti-coagulant and will promote blood clotting. Sodium oxalate and heparin containing test tubes will not allow the blood to clot.

Explanation:
The correct answer is option 'A' - Test tube containing calcium bicarbonate.
Reasons why this test tube cannot be used for the purpose are:
1. Calcium bicarbonate test tube is used for collecting blood for glucose estimation, not for analysis of blood corpuscles and plasma.
2. Calcium bicarbonate is a chemical used to preserve blood for glucose estimation. It prevents the breakdown of glucose and stabilizes it for up to 48 hours. However, it can interfere with the analysis of blood corpuscles and plasma, leading to inaccurate results.
3. The other three test tubes - chilled test tube, test tube containing heparin, and test tube containing sodium oxalate are commonly used for collecting blood for analysis of blood corpuscles and plasma.
- Chilled test tube is used for collecting blood for coagulation studies.
- Heparin test tube is used for collecting blood for plasma protein analysis and clotting factor assays.
- Sodium oxalate test tube is used for collecting blood for hematological tests like complete blood count (CBC) and erythrocyte sedimentation rate (ESR).
Conclusion:
Thus, it is important to choose the appropriate test tube for the specific blood test required to ensure accurate results. In this case, the test tube containing calcium bicarbonate is not suitable for the analysis of blood corpuscles and plasma.

For this we don't want to coagulate blood so ,here calcium carbonate clot blood but other three factors will not coagulate the blood
As Ca combine with heparin natural anticoagulant present in blood and promote blood coagulation
As Ca combine with heparin natural anticoagulant present in blood and promote blood coagulation
