The correct answer is A. Boat : Oars.
A postcard is a piece of card with a picture on one side and space for a message on the other. It is typically sent through the mail to someone who lives far away. Oars are long, thin pieces of wood or metal that are used to row a boat.
In the same way, a boat is used to travel on water, and oars are used to propel a boat through the water. Similarly, a postcard is used to send a message to someone who lives far away, and the postal service is used to deliver the postcard.
The other options are not correct because they do not have the same relationship as the original pair of words.
- Flower : Bunch is not a correct pair because a flower is not used to make a bunch. A bunch is a group of things that are held or tied together, and a flower is a single plant that has petals, sepals, and a stamen.
- Shirt : Blouse is not a correct pair because a shirt is not used to make a blouse. A blouse is a type of shirt that is typically worn by women, and a shirt is a piece of clothing that is typically worn by men.
- Pillow : Cot is not a correct pair because a pillow is not used to make a cot. A cot is a small bed that is typically used by children, and a pillow is a soft cushion that is used to support the head or neck when sleeping.
