Answer:

There were small crinkles at the corners of her eyes.

Explanation:

Duchenne smile, also known as genuine smiles, was named after the French Neurologist. <u>The name of this French Neurologist was Guillaume Duchenne de Boulogne</u>. He studied the facial expressions in the nineteenth century in which he discovered that a genuine smile can be identified by observing two things.

He asserted that when a person smiles genuinely, two facial muscles are involved namely, Zygomatic major muscle and Orbicularis oculi muscle.

  • Zygomatic major muscle is located around the cheek and uplifts the corners of the lip.
  • Orbicularis oculi muscle helps in contraction of eye area that produces 'crow's feet' or the wrinkles around the eyes.

<u>So, according to the theory of Duchenne smile, a genuine smile will have a cheeks lifted and a natural crinkle around the eyes</u>.

So, the correct answer is the third option.
