Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
The statement that is true as per widely accepted theories is that the landmass of Pangaea split into separate continents over time. The correct option is B.
<h3>What is Pangaea theory?</h3>
According to National Geographic, the Pangaea theory proposed that the tectonic plates that make up the planet's outer crust drifted over the inner layers until they merged as a landmass surrounded by a massive ocean called Panthalassa.
The existence of Pangea was first proposed by German meteorologist Alfred Wegener in 1912 as part of his theory of continental drift. Its identity is inferred from the Greek pangaia, which means "the entire Earth."
Thus, the correct option is B.

Diploblastic and triploblastic embryos.
During embryogenesis, diploblasts develop two embryonic germ layers: an ectoderm and an endoderm or mesendoderm. Triploblasts develop a third layer—the mesoderm—which arises from mesendoderm and resides between the endoderm and ectoderm.
