The plant hormone that promotes the acquisition of desiccation tolerance in developing seeds is abscisic acid (ABA).

Abscisic acid plays a crucial role in various aspects of plant development and responses to environmental stresses, including the regulation of seed dormancy and germination. During seed development, ABA accumulates in maturing seeds and promotes the acquisition of desiccation tolerance.

As the seed matures, ABA levels increase, triggering physiological and biochemical changes that prepare the seed for dormancy and withstand periods of water scarcity. ABA inhibits seed germination, preventing premature germination under unfavorable conditions and allowing the seed to remain dormant until suitable conditions for germination are present.

Hence, the correct answer is option 1.
