Ostentation is the pretentious or showy display of wealth and luxury, designed to impress.
I think the answer is going to be B. not sure
<span>The answer would be luc, lum, lun & lus. Since they all came from Latin lux, lucis & lume which means all light. Luminary, to bring light to the eye or luminescence which means a giving out of light by a material not coming from heat. Lucent means to produce light. So any word that has those Latin roots can be an invention's name.</span>
