Correct option is A
Assertion 'A' states that the theories of price determination under oligopoly are found to be inapplicable to real-life market conditions. This statement is correct.
Reason 'R' provides an explanation for Assertion 'A' by stating that real-life oligopoly market situations are characterized by a small number of sellers, interdependence of decision making, barriers to entry, indeterminate price and output, which all lead to a wide variety of situations. This explanation is also correct and supports Assertion 'A'.
Therefore, option (a) is the correct answer.
