Water drops in a dispersion medium of air.<\/p>\n<p>A colloid is a mixture of two or more substances where one substance of microscopically dispersed insoluble particles is suspended throughout another substance. The particles of the dispersed phase have a diameter between 1 and 1000 nanometers. The dispersed phase is called the colloidal phase, and the medium in which it is dispersed is called the dispersion medium.<\/p>\n<p>Clouds are formed when water vapor in the air condenses around tiny particles of dust or salt. These particles act as nuclei for the water droplets to form on. The water droplets are so small that they remain suspended in the air, and they reflect and scatter sunlight, which is why <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> we see clouds.<\/p>\n<p>Option A is incorrect because air is the dispersion medium in a cloud, not the dispersed phase.<\/p>\n<p>Option B is incorrect because fog is a type of cloud that forms when water vapor condenses in the air near the ground.
