Explanation

Pest control via human activities and laws typically refers to regulatory or legal methods. 'Regularity method' is likely a typo for 'Regulatory method'. Among the options, physical methods involve manual/mechanical control, but none perfectly fit 'law'. However, 'Regulatory' is standard. Since 'Regularity' is clearly wrong, and no 'Regulatory' option exists, this question might be flawed or refer to a specific local curriculum term. Given the options, none are ideal for 'law', but physical methods involve human intervention. Wait, let's reconsider. Pest control methods: Cultural, Chemical, Biological, Physical/Mechanical, Regulatory/Legal. The question mentions 'human controlling activities and law'. This strongly points to Regulatory method. Option A says 'Regularity method', which is almost certainly a typo for 'Regulatory method'. If we assume it's a typo, A is the intended answer. However, strictly speaking, 'Regularity' is not a standard term. I will flag it for review because of the likely typo making it ambiguous.
