Wajib pajak belum menikah dan suami sebagai kepala keluarga adalah kelompok WP OP __ A Induk B HB C square D square

The correct answer is **B. HB**.Here's why:* **WP OP** stands for "Wajib Pajak Orang Pribadi" (Individual Taxpayer) in Indonesian.* **HB** stands for "Head of Family" (Kepala Keluarga).Since the taxpayer is unmarried but their husband is the head of the family, they fall under the "Head of Family" category for individual taxpayers. Let me know if you have any other questions!
