According to Section 101 of the Bharatiya Sakshya Adhiniyam, 2023, which statement correctly defines the burden of proof?

Section 101 of the BSA provides: "Whoever desires the Court to give judgment as to any legal right or liability, dependent on the existence of certain facts, must prove that those facts exist." This establishes the fundamental principle: the party asserting a legal right or liability bears the burden of proving the foundational facts. The burden is  static and fixed —it does not shift based on evidence presented (that shifting mechanism is the "onus of proof" under Section 102). Section 101 allocates responsibility: the party with the legal interest in proving a proposition bears the burden throughout the proceeding.
