Step 1: Understand the format of the question.
This is an Assertion-Reason question. We need to check whether each statement is correct, and if both are correct, whether the Reason logically explains the Assertion.
Step 2: Evaluate Assertion (A).
Assertion (A) says: General forces such as social, political, legal and technological conditions affect an individual firm only indirectly. This is a well-established fact in business environment theory. General forces do not target a single firm; their impact is broad and indirect across all businesses. So, Assertion (A) is correct.
Step 3: Evaluate Reason (R).
Reason (R) says: General forces have an impact on all business enterprises, in contrast to specific forces that affect individual firms directly and immediately in their day-to-day working. This is also a textbook-accurate statement. General forces are economy-wide and industry-wide, while specific forces (like customers or suppliers) affect a particular firm's daily operations directly. So, Reason (R) is also correct.
Step 4: Check whether R explains A.
Assertion A says general forces affect a firm only indirectly. Reason R explains exactly why: because these forces act on all enterprises broadly rather than targeting any one firm directly. The broad, all-encompassing nature of general forces (stated in R) is the direct reason for why they only affect individual firms indirectly (stated in A). So R is the correct explanation of A.
Step 5: Match with the options.
Both A and R are correct, and R correctly explains A. This matches option (A).
Step 6: Conclude.
The relationship between specific and general forces is clear: the indirect nature of general forces on individual firms exists because these forces apply to every enterprise, not just one.
\[ \boxed{ \text{(A) Both Assertion (A) and Reason (R) are correct and Reason (R) is the correct explanation of Assertion (A).} } \]
