Answer: (A)

Verified step by step guidance

1. Step 1: Understand the question by identifying that it is asking about the type of cancer responsible for the most deaths in both males and females. This requires knowledge of cancer statistics and epidemiology.
2. Step 2: Recall that lung cancer is widely recognized as the leading cause of cancer-related deaths globally for both males and females due to its aggressive nature and late-stage diagnosis.
3. Step 3: Compare lung cancer with other types of cancer listed in the options (prostate cancer, breast cancer, and colorectal cancer). Note that prostate cancer primarily affects males, breast cancer primarily affects females, and colorectal cancer affects both genders but has lower mortality rates compared to lung cancer.
4. Step 4: Consider the biological and environmental factors contributing to lung cancer's high mortality rate, such as smoking, air pollution, and genetic predisposition, which make it more prevalent and deadly.
5. Step 5: Conclude that lung cancer is the correct answer based on its statistical significance in causing the most deaths in both males and females, supported by epidemiological data.
