The correct option is A.
Resonance is the phenomenon by which a vibrating system or an external force drives another system to oscillate with greater frequencies at specific frequencies. These specific frequencies are called resonant frequencies. At resonance frequencies, small periodic driving forces have capacity to produce large amplitude oscillation.<span />

However a standard method to dertmine how workload effects health is developed and is called Harvard step test.
The Harvard Step Test is a fitness test method devised to measure heart and respiratory fitness. It is done by giving some work load to a person for 5 minutes (normally) and then noting his heart rate afterwards in some intervals.
Formula is;
Fitness Index = (100 x test duration in sec) / (5.5 x pulse count between 1 and 1.5 mins)

The answer is TOSH.
Tropical, subtropical, temperate, and alpine vegetation can all be found in the Himalayas, and each variety predominates in a region primarily influenced by elevation and precipitation. The species found in each zone vary significantly due to local variations in relief, climate, and exposure to wind and sunlight.
- The humid Himalayan foothills in the east and center are the only places where tropical evergreen rainforest can be found. The evergreen dipterocarps, a group of common trees that produce resin and timber, thrive on a variety of soil types and steepnesses in hill slopes. Oaks (genus Quercus) and Indian horse chestnuts (Aesculus indica) grow on the lithosol (shallow soil made up of imperfectly weathered rock fragments), which covers sandstones from Arunachal Pradesh westward to central Nepal at elevations of 3,600 to 5,700 feet. Mesua ferrea, a species of Ceylon ironwood, grows on porous soils between 600 and 2,400 feet (180 and 720 metres) (1,100 to 1,700 metres). On the steeper slopes, alder trees (genus Alnus) can be found growing alongside watercourses. Higher elevations cause certain species to succumb to mountain woods, where Himalayan screw pine serves as the predominant evergreen (Pandanus furcatus). Aside from those trees, it is thought that the eastern Himalayas are home to 4,000 species of blooming plants, 20 of which are palms.
