Hili hapa suluhisho la swali lako: Step 1: Elewa maana ya nambari tasa (prime number). Nambari tasa ni nambari kamili iliyo kubwa kuliko 1 ambayo inaweza kugawanywa tu na 1 na yenyewe. Step 2: Chunguza kila chaguo na utambue nambari tasa kati ya 30 na 50. Nambari tasa kati ya 30 na 50 ni: 31, 37, 41, 43, 47. Sasa, hebu tuchunguze kila chaguo: A. 31, 33, 37, 41 31 ni tasa. 33 si tasa (33 = 3 × 11). Hivyo, chaguo A si sahihi. B. 31, 37, 41, 43, 47 31 ni tasa. 37 ni tasa. 41 ni tasa. 43 ni tasa. 47 ni tasa. Nambari zote katika kundi hili ni tasa. Hivyo, chaguo B ni sahihi. C. 31, 39, 41, 47 31 ni tasa. 39 si tasa (39 = 3 × 13). Hivyo, chaguo C si sahihi. D. 33, 35, 37, 39 33 si tasa (33 = 3 × 11). 35 si tasa (35 = 5 × 7). 39 si tasa (39 = 3 × 13). Hivyo, chaguo D si sahihi. Step 3: Chagua kundi lenye nambari tasa pekee. Kundi pekee lenye nambari tasa pekee kati ya 30 na 50 ni chaguo B. Jibu la mwisho ni: B 3 done, 2 left today. You're making progress.
