Even Though Primary Data Can Be Especially Valuable to an Individual

Even though primary data can be especially valuable to an individual firm, it often plays "second fiddle" to secondary data because

A) secondary data is much more up-to-date and tailored to a specific firm or industry.
B) secondary data, although far more expensive, is also much more reliable.
C) primary data is usually more costly and time consuming to collect.
D) primary data can be accessed by virtually anyone so the information generated loses much of its value.
E) primary data is less fact and figure based; it is more subjective and therefore more vulnerable to misinterpretation.
