Step 1: Understanding the Concept:
Safflower (*Carthamus tinctorius*) is an economically important oilseed crop grown primarily for its high-quality edible oil, which is rich in polyunsaturated fatty acids (specifically linoleic acid).
Step 2: Detailed Explanation:
The seeds of modern cultivated safflower varieties typically contain an oil content ranging between \(35\%\) and \(45\%\) on a dry weight basis.
The oil extracted is highly valued for its health benefits, containing up to \(75\%\) linoleic acid, which helps lower blood cholesterol levels.
Step 3: Final Answer:
The average oil content in Safflower seeds is \(35\text{--}45\%\), corresponding to option (C).
