What is the demand curve in a purely competitive industry?

A perfectly competitive firm's demand curve is a horizontal line at the market price. This result means that the price it receives is the same for every unit sold.

Which of the following statements is correct about the demand curve of the perfectly competitive industry?

The correct option is D. The market demand curve of the perfectly competitive industry is downward-sloping while the demand curve facing an individual firm is horizontal.

Which of the following statements is correct purely competitive?

The correct answer is b) A purely competitive firm is a "price-taker" and a monopolistic firm is a "price-maker". A single competitive firm can't influence the market decision as it plays a very small role in the market. A competitive market has a large number of small firms operating in the market.

Is the demand curve for a purely competitive firm elastic?

All goods in a perfectly competitive market are considered perfect substitutes, and the demand curve is perfectly elastic for each of the small, individual firms that participate in the market. These firms are price takers–if one firm tries to raise its price, there would be no demand for that firm's product.
