Researchers in the field of biomechanics discover new and effective ways to perform a skill or  a sport based on their analysis of body movement

Option C

Explanation:

 Biomechanics is a field which is concentrated to effectively improve the skills and output of a sports man. Here small techniques are taught to uplift the performance. The skilled teachers and coaches research and discover new and effective ways by trial and error method by observing and implementing the best technique which would be apt to increase the skills.

Body movement in a perfect way that is the call of the hour which requires consistency in the sports performance. How the body movement when aligned can trigger the performance of the individual is researched through biomechanics.

i think its pulmonary not sure tho

the answer is a
