Which individual is recognized as "Ina ng Biac na Bato" during the Philippine Revolution?

The recognition of Melchora Aquino as "Ina ng Biac na Bato" stems from her significant contributions during the Philippine Revolution. Known for her role in providing support to the revolutionary forces, she was a key figure in the Biak-na-Bato Republic and is often referred to as the "Mother of the Philippine Revolution”. Her efforts included caring for sick and wounded soldiers and facilitating the sustenance of the revolutionary fighters, highlighting her importance in the history of the struggle for independence.

In contrast, while the other individuals played important roles during the Philippine Revolution, they are not associated with the title of "Ina ng Biac na Bato." Aguenda Kahabagan, for instance, is remembered for her involvement in military activities but does not have the maternal designation. Rosa Sevilla de Alvero was known for her educational efforts and advocacy for women's rights, which were significant in their own right but do not directly correlate with the title in question. Trinidad Tecson, although also a notable figure in the revolution, does not bear the same recognition as Aquino. Thus, Melchora Aquino remains the correct answer for her well-documented historical legacy and symbolic role as the mother figure of that pivotal moment in Philippine history.
