The correct option is D Girls should change pad after every 4-5 hours.
Girls should take special care of cleanliness during menstruation. To prevent infections, they should change pads frequently as once in every 4-5 hours. There are many different kinds of pads like thick homemade cloth pads or ready to use cotton and plastic made pads or biodegradable cotton pads. Depending upon the needs, they could use any but proper cleaning or disposal is a must. There are several myths and taboo's surrounding menstruation. We must understand that they are not scientific at all.
∙ Girls can maintain personal hygiene and work in kitchen.
∙ A menstruating girl does not get pregnant if she looks at a boy. For getting pregnant, fertilisation of her ovum with a sperm must take place.
∙ Sex is determined by the sex chromosome of the boy. If the sperm contains X chromosome, then the zygote would develop into a male child after fertilisation. So, receiving a girl or boy can not be pre-decided.
