Final answer:
Happiness is the quality not attributed to Hrothgar in 'Beowulf', as the epic poem shows his character as generous, wise, and courageous, but not specifically happy.
Step-by-step explanation:
The qualities of Hrothgar as represented in Beowulf include generosity, wisdom, and courage. Hrothgar, the king of the Danes, is widely respected and is shown throughout the epic poem as a generous and wise ruler, as well as a courageous leader in his younger days. However, the quality of happiness is not explicitly mentioned as one of Hrothgar's characteristics in the poem. Instead, Hrothgar is often portrayed as being troubled by the attacks on his kingdom by the monster Grendel, suggesting that while he might have moments of happiness, it is not a defining characteristic. Therefore, the answer is 'a. Happiness' since that is not a quality attributed to Hrothgar in Beowulf.
