The correct answer is: A. Principal ZRTI.
A block competency certificate is issued by the Principal ZRTI. The Principal ZRTI is the head of the ZRTI (Zonal Regional Training Institute). The ZRTI is responsible for training and certifying teachers in the zone. The block competency certificate is a certificate that is issued to teachers who have successfully completed the ZRTI training program. The certificate is proof that the teacher has the skills and knowledge necessary to teach in the zone.
The other options are incorrect because:
- SM stands for Subject Matter Expert. The SM is not responsible for issuing block competency certificates.
- AOM stands for Assistant Operations Manager. The AOM is not responsible for issuing block competency certificates.
- None of these is the correct answer because the Principal ZRTI is the only person who is authorized to issue block competency certificates.
