Step 1: Understanding the Concept
Granulocytes are named by the dye they take up. Acidophils are eosinophils and cyanophils are basophils.
Step 2: Check Statement I
Acidophils do not secrete histamine. They release histaminase and help to counter allergic reactions, so Statement I is incorrect.
Step 3: Check Statement II
Cyanophils secrete histamine, serotonin and heparin, which promote inflammation. They are not anti-histaminic, so Statement II is incorrect.
Step 4: Choose the option
Both statements are incorrect, which is option (B).
Final Answer:
Both statements are incorrect.
\[ \boxed{\text{(B) }\text{Both statement I and statement II are incorrect.}} \]
