<u>Explanation</u>:
Depending upon the involvement shown in buying the products, the type of buying decision making can be categorized as:
• Routine response behavior
• Limited decision making
• Extensive decision making.
<u>Routine response behavior </u>is exposed when the consumer is familiar with the product to-be-purchased and also on purchasing low cost goods. Generally people will show less involvement in frequently buying products.
<u>Extensive Decision Making </u>occurs while purchasing the expensive product. These products are unfamiliar and are not bought frequently. So their involvement level will be high.
