Concept: In library acquisition work, book supply terms are important because libraries purchase books from publishers, vendors and booksellers. Uniform terms help in maintaining fairness, standardization and transparency in book supply.
Step 1: Understanding the role of Good Offices Committee.
Good Offices Committee is associated with book trade and library supply matters. It worked towards establishing uniform and fair terms of book supply to libraries.
\[
\text{GOC} \Rightarrow \text{Uniform terms of book supply}
\]
Step 2: Checking other options.
UGC is related to higher education and university grants.
Raja Ram Mohan Rai Library Foundation supports public libraries.
A general library committee may help in library administration, but it is not specifically known for uniform terms of book supply.
Step 3: Selecting the correct organization.
Since the question directly asks about uniform terms of book supplies to libraries, the correct answer is Good Offices Committee.
Therefore, the correct answer is option (A).
