SAARC (South Asian Association for Regional Cooperation) currently has 8 member countries. These are Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, Sri Lanka, and Afghanistan.

Hazrat Umar (Umar ibn Al-Khattab) was born in 584 AD, which is before the Hijri calendar started (622 AD). Therefore, it is incorrect to say he was born on a specific Hijri date.

Option A gives his birth year in AD, which is correct, but the question asks 'on which hijri?', implying a Hijri date, so the best answer is D (None of these).

TikTok was originally launched in China as Douyin in September 2016. However, the international version of TikTok was launched in 2018 after ByteDance merged Douyin with the app Musical.ly, which it had acquired in 2017. Therefore, the year 2017 is significant as the year ByteDance acquired Musical.ly, but TikTok as an international app was launched in 2018. Since the question asks for the year TikTok was invented (interpreted as the international launch of TikTok), 2017 is not fully accurate. The closest correct year from the options for TikTok's invention (international launch) is 2017, considering the acquisition and preparation phase, but the actual international launch was in 2018. Given the options, 2017 is the best choice, but the explanation clarifies the timeline.
