The observation that led Alfred Wegener to develop the hypothesis of continental drift was that the continents looked like a puzzle that could fit together and then found out that fossils of similar kind and whats left of similar plants were found on opposite sides of the world.
Alfred Wegener noticed that the outlines of the continents seemed to fit together like pieces of a jigsaw puzzle, particularly the coastlines of South America and Africa. This observation led him to develop the theory of continental drift.

Wegener used evidence from fossils, rock formations, and the fit of the continents as key components to develop his theory of continental drift. By studying these factors, he proposed the idea that all continents were once part of a single supercontinent called Pangaea.
Alfred Wegener used fossil evidence, particularly the presence of identical plant and animal fossils on continents that are now separated by oceans, to develop the theory of continental drift. This suggested that those continents were once joined together.

Yes, Wegener did use evidence of glacial striations to support his theory of continental drift. He observed that matching glacial striations on continents separated by oceans suggested they were once connected and had moved apart. This was one of the pieces of evidence Wegener used to develop his theory of plate tectonics.
One piece of evidence that led Wegener to propose the theory of continental drift was the observation that the coastlines of Africa and South America appeared to fit together like puzzle pieces. This suggested that the continents were once joined together and had subsequently drifted apart.
No, Alfred Wegener did not use sea-floor spreading, ridge push, or slab pull to develop his hypothesis of continental drift. Wegener proposed his theory in 1912, long before these concepts were formulated in the mid-20th century as part of the theory of plate tectonics. Instead, Wegener based his hypothesis on evidence such as the fit of continental coastlines, fossil distribution, and geological similarities across continents. The mechanisms of sea-floor spreading and plate tectonics were developed later to explain the movement of continents.

When you look at a map of the continents you find that the East coast of South & Central America line up with the Western coast of Africa. With how clearly they match each other, it supported his hypothesis.
