How oftens should linens be washed ? daily, weekly unless soiled, when the linens start to smell, bi-weekly

Bis the answer hope i  

The primary concern is a likely carbon monoxide gas leak. the boy arrived home and soon started to feel sick. since carbon monoxide poisoning symptoms appear sooner in adolescents than in adults, we can use the boy’s age, 16, to determine that there is carbon monoxide present in the house. the dispatcher should let the responders arriving at the house to take caution when entering and to wear a gas mask until the presence of carbon monoxide is confirmed.

Ithink b is the best answer.
