The Correct Option is C

Solution and Explanation

Step 1: Understanding the spatulation process. - Spatulation is a gentle mixing technique using a spatula on a smooth surface. - It is used for mixing powders that are prone to liquefaction upon contact.

Step 2: Explanation of incorrect options. - (A) Hygroscopic: These absorb moisture and require special handling. - (B) Volatile: Best handled in closed containers, not with spatulation. - (D) Effervescent: Reacts with moisture; requires minimal handling to prevent premature reaction.

Step 3: Selecting the correct option. Since eutectic mixtures tend to liquefy upon contact, the correct answer is (C) Eutectic.
