a) <figure>
b) <src>
c) <alt>
d) <title>

Answer: a
Explanation: An alt attributes gives a text description of the image if the image is not available at a time. An address of image is defined by src attribute. HTML5 has introduced new element named <figure>. It contains image and its caption and hence both are associated with each other. We can also have more than one image inside <figure> element and they share the same caption.
