A non-stock, non-profit school always had cash flow problems, resulting in failure to recruit well-trained administrative personnel to effectively manage the school. In 2010, Don Leon donated P100 million pesos to the school, provided the money shall be used solely for paying the salaries, wages, and benefits of administrative personnel. The donation represents less than 10% of Don Leon's taxable income for the year. Is he subject to donor's taxes? a. No, since the donation is actually, directly, and exclusively used for educational purposes. b. Yes, because the donation is to be wholly used for administration purposes. c. Yes, since he did not obtain the requisite NGO certification before he made the donation. d. No, because the donation does not exceed 10% of his taxable income for 2010
