Maximum amount of weed seed permitted in rice seed for getting certified:

Correct option is B

✔️ (b) 20 seeds / kg: As per the Indian Minimum Seed Certification Standards (IMSCS) for certified rice seeds, the maximum weed seed content allowed is 20 seeds per kg.
· This standard ensures that the seed lot is relatively clean and free from contaminating weeds
· Above this limit, the seed lot is rejected for certification
❌ (a) 0 seeds / kg: Zero tolerance is practically impossible and not realistic for certified seed standards.
❌ (c) 5 seeds / kg: Too stringent; such low limits apply to foundation or breeder seeds, not certified seed.
❌ (d) 15 seeds / kg: This is still lower than the certified seed standard; correct limit is 20 seeds/kg for rice.
