A zero arc elasticity indicates that the quantity demanded is not affected by a change in price.<\/p>\n<p>The arc elasticity of demand is a useful tool for businesses to understand how consumers will respond to changes in price. It can also be used to compare the responsiveness of different goods and services to changes in price.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: This option is incorrect because it divides the percentage change in quantity demanded by the percentage change in price, but then adds the two quantities together. This does not make sense mathematically.<\/li>\n<li>Option B: This option is incorrect because it divides the percentage change in quantity demanded by the percentage change in price, but then subtracts the two quantities together. This also does not make sense mathematically.<\/li>\n<li>Option C: This option is correct because it divides the percentage change in quantity demanded by the percentage change in price, and then divides the result by the average of the <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> initial and final prices.
