**Core Concept**
Blood coagulation disorders in obstetrics can be assessed through various laboratory tests and clinical observations. Disseminated intravascular coagulation (DIC) and fibrinolytic process are two conditions that can affect blood coagulation in pregnant women. Identifying the correct relationship between these conditions and thrombocytopenia is crucial in obstetric care.

**Why the Correct Answer is Right**
Option A is correct because thrombocytopenia is actually a feature of DIC, not fibrinolytic process. In DIC, platelets are consumed due to the formation of microthrombi, leading to thrombocytopenia. The fibrinolytic process, on the other hand, involves the breakdown of fibrin clots and is not directly associated with thrombocytopenia. This distinction is essential in diagnosing and managing coagulopathy in obstetrics.

**Why Each Wrong Option is Incorrect**
**Option B:** This statement is incorrect because in the fibrinolytic process, RBCs can be fragmented or schistocytes can be seen due to mechanical damage within the microcirculation, but the cell morphology is not nominal. In DIC, RBC morphology can be affected due to the formation of microthrombi.

**Option C:** This statement is correct, and we'll keep it out of the "wrong options" section. However, it's worth noting that the Weiner clot observation test is actually used to assess the clotting time and not the fibrinogen level directly.

**Option D:** This statement is incorrect because thrombocytopenia can be diagnosed from the peripheral smear by observing a low platelet count or the presence of platelet clumps.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that DIC should be suspected in obstetric patients with unexplained thrombocytopenia, coagulopathy, and evidence of microvascular thrombi on imaging studies.

**✓ Correct Answer: A. Thrombocytopenia is a feature of fibrinolytic process and not of DIG**
