{Walking:} A simple and effective aerobic exercise.
{Swimming:} A great full-body aerobic workout.
{Exercise (general):} Includes many activities that strengthen the cardiovascular system. Since all listed items are forms of physical activity known to be beneficial for heart health, "All of these" is the correct choice.

Answer 1

The Correct Option is D

Concept: This question asks to identify activities that are beneficial for heart health. Regular physical activity is widely recognized as important for cardiovascular health. Step 1: Analyze the benefits of each option for heart health
(1) Walking: Walking is a low-impact aerobic exercise that improves cardiovascular fitness, helps control blood pressure, reduces bad cholesterol (LDL), increases good cholesterol (HDL), and helps manage weight. It is definitely good for the heart.
(2) Exercise: This is a general term encompassing various physical activities designed to improve health and fitness. Many forms of exercise, especially aerobic exercises, are beneficial for the heart.
(3) Swimming: Swimming is an excellent aerobic exercise that provides a full-body workout, improves cardiovascular endurance, strengthens the heart muscle, and can help lower blood pressure. It is very good for the heart. Step 2: Evaluate the option "All of these" Since walking, general exercise, and swimming are all individually known to be good for the heart, the option "All of these" accurately reflects that each listed activity contributes positively to heart health. "Exercise" is a broad category that includes walking and swimming. Therefore, "All of these" is the most appropriate answer as each specific activity (walking, swimming) and the general category (exercise) are beneficial for the heart.
