Step 1: Examine Statement (a).
Statement (a):
“It involves transactions between two consumers.”
This statement accurately describes the fundamental feature of the C2C model. Both the buyer and seller are consumers rather than business organizations.
Therefore,
\[
{\text{Statement (a) is Correct}}
\]
Step 2: Examine Statement (b).
Statement (b):
“Online platforms like OLX facilitate C2C trade.”
OLX is a well-known platform where individuals can directly buy and sell products such as vehicles, furniture, electronics, and household goods.
Hence, OLX is a classic example of a C2C marketplace.
Therefore,
\[
{\text{Statement (b) is Correct}}
\]
Step 3: Examine Statement (c).
Statement (c):
“It reduces dependency on traditional retailers.”
Since consumers can directly purchase products from other consumers, they often bypass traditional retail stores and intermediaries.
Thus, C2C platforms provide an alternative channel for buying and selling goods.
Therefore,
\[
{\text{Statement (c) is Correct}}
\]
Step 4: Examine Statement (d).
Statement (d):
“Businesses directly supply goods and services to customers in this model.”
This statement describes the Business-to-Consumer (B2C) model rather than the Consumer-to-Consumer (C2C) model.
In B2C, companies sell directly to end consumers. Examples include Amazon Retail, Flipkart, and company-owned online stores.
Therefore,
\[
{\text{Statement (d) is Incorrect}}
\]
Step 5: Determine the correct combination.
From the above analysis:
\[
(a) = \text{Correct}
\]
\[
(b) = \text{Correct}
\]
\[
(c) = \text{Correct}
\]
\[
(d) = \text{Incorrect}
\]
Hence, the correct set of statements is:
\[
(a), (b), \text{and } (c)
\]
which corresponds to:
\[
{\text{Option (A)}}
\]
Conclusion:
The C2C e-business model involves transactions between consumers, is facilitated by platforms such as OLX, and reduces reliance on traditional retailers. Therefore, statements \((a)\), \((b)\), and \((c)\) are correct.
Hence, the correct answer is:
\[
{\text{Option (A)}}
\]
