The correct answer is 'A'. All mammals produce milk to nourish their young.

Explicación

## Step 1The question asks us to identify a common characteristic among all mammals in terms of how they raise their offspring. The options provided are:- They produce milk to nourish their young.- They give birth to live young.- They use pouches to care for newborns.- They lay eggs.## Step 2We need to evaluate each option based on the known characteristics of mammals.## Step 3The first option, "They produce milk to nourish their young," is a characteristic of all mammals. This is because all mammals have mammary glands that produce milk young.## Step 4The second option, "They give birth to live young," is not a characteristic of all mammals. While most mammals give birth to live young, there are exceptions such as monotremes (like the platypus and echidna) which lay eggs.## Step 5The third option, "They use pouches to care for newborns," is not a characteristic of all mammals. This is a characteristic of marsupials, a specific group of mammals, but not all mammals.## Step 6The fourth option, "They lay eggs," is not a characteristic of all mammals. This is a characteristic of reptiles and birds, not mammals.
