Answer:
The correct answer is - b,d,c,a
Explanation:
Enveloped virus are amongst the most sensitive micro-organisms because it contains lipid membrane which is easily degraded and destroyed by antimicrobial agents like ethanol.
Then gram-negative bacteria comes for which some antibiotics can be used to kill it. Mycobacterium is resistant to most of the antibiotics and comes under multiple drug-resistant bacteria because of having thick and waxy outer layer and enzymes that degrade antibiotics.
Prions are the infectious proteins and are most resistant to antimicrobial agents because it is non-cellular and are can withstand high temperature and resist enzyme degradation. Therefore, the right answer is-b,d,c,a.

b. Breastfeeding and child-rearing techniques were followed by the hunter-gatherers for the birth spacing interval.
Explanation:
The birth spacing interval among hunter-gatherer population was simply achieved by mother’s breastfeeding pattern and child-rearing and weaning techniques without the use of any contraceptives.
Mothers breastfed their infants nearly for the first two years of infancy. The constant round-the-clock sucking of the infants during breastfeeding led to hormonal changes leading to suppression of ovulation in a lactating mother.
Among nomadic hunter-gatherer groups, women carried their infants in a pouch on their backs while the men went for hunting. So close birth spacing required the mother to carry, wean and rear both the children at one time which would cause a heavy burden for the mother. Further, the energy expenditure during pregnancy and lactation also has to be covered.
Hence, the mothers breastfed the infant for longer periods which helped them in birth spacing.
