Answer:
d) hera
Step-by-step explanation:
In Greek mythology, Hera was the wife of Zeus, the king of the gods. Heracles, being the son of Zeus and a mortal woman, was a constant reminder of Zeus's infidelity to Hera, which fueled her resentment towards him.
Hera played a significant role in Heracles' life, often causing him great suffering and attempting to thwart his heroic endeavors. She sent various monsters and obstacles to hinder him, such as the Nemean Lion, the Hydra, and the Ceryneian Hind. Additionally, she drove Heracles into a fit of madness, leading him to kill his own wife and children.
Hera's animosity towards Heracles stemmed from her personal vendetta against him as a symbol of Zeus's indiscretions. She remained one of his primary adversaries throughout his legendary twelve labors and his overall heroic journey.
