a. a symbol of hospitality, friendliness, warmth and cheer

Explanation:

In colonial America, hosts would set a fresh pineapple in the center of their dining table when visitors joined their families in their homes. Gatherings such as these were the primary means of entertainment and cultural exchange, and as a result the concept of hospitality became a central element in colonial life. The pineapple, then, symbolized the warmest welcome hosts could extend to their guests. As time has passed the pineapple has been internationally recognized as a symbol of hospitality and a symbol of friendliness, warmth, and cheer.

A. a symbol of hospitality, friendliness, warmth and cheer Explanation:

The Pineapple is native to South America and was transport to Europe by the first explorers. As popularity grew, it had been featured in architecture, art, and furniture. Following a life at sea people placed a pineapple on their porch, door, or entrance after coming back from an extended voyage, welcoming visitors into their home to celebrate, announcing to all or any "Our voyage is over, our door is open, food and drink for everyone!" Thus the pineapple has become a world symbol of hospitality and is widely displayed in residences and business establishments, extending a warm welcome to all or any that visit.
