Marginal revenue is
the change in total revenue brought about by selling an additional unit of the good.

the marginal revenue curve lies below the demand curve.
In the theory of perfect competition,
the single firm's demand curve is horizontal. and the market demand curve is downward sloping. (b and d)

Each firm produces and sells a differentiated product.
Firm X is a single seller of good X. There are, however, two substitutes for good X. Given this,

No, because at its chosen quantity of output, price is greater than marginal cost
Does a real-world market have to meet all the assumptions of the theory of perfect competition before it is considered a perfectly competitive market?
No, probably no real-world market meets all the assumptions of the theory of perfect competition. All that is necessary is that a real-world market behave as if it satisfies all the assumptions.
