<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A study looking to examine the utility of colorectal cancer screening in patients younger than 50 is currently seeking subjects to enroll. A 49-year-old man with a family history of colorectal cancer is very interested in enrolling in the study, due to his own personal concerns about developing cancer. If enrolled in this study, which of the following types of biases will this represent?? A: Measurement bias, B: Recall bias, C: Lead-time bias, D: Selection bias, E: Length bias,  <response>: This is a question about types of bias in medical research. The scenario describes a 49-year-old man with a family history of colorectal cancer who wants to enroll in a study about colorectal cancer screening in people under age 50. His personal concerns about developing cancer may make him different from the general population of people under 50, so his participation could introduce bias into the study results.The answer choices list different types of bias. Measurement bias refers to errors in how data is measured or collected. Recall bias refers to errors in participants recall or reporting of information. Lead-time bias refers to early detection due to screening appearing to extend survival time. Length bias refers to over-representation of slower-progressing cases due to early detection from screening. The type of bias introduced by self-selection of a participant with high personal risk is selection bias. Therefore, the correct answer is D.D: Selection bias
