Whales have pelvic (hip) bones, which are evolutionary remains from when their forefathers walked on land about 40 million years ago. Common belief has long assumed that such bones are merely vestigial, slowly withering away like human tailbones. Thus option C is correct.

<h3>What is the new research from USC and the Natural History Museum of Los Angeles County (NHM) has to say ?</h3>

New research from USC and the Natural History Museum of Los Angeles County (NHM) contradicts this belief, discovering that not only do those pelvic bones have a role, but their size and perhaps shape are impacted by sexual selection processes.

Therefore, small, shrunken hip bones of whale are no longer beneficial for survival and are considered vestigial. So, the best option is C among the other options available. Thus option C is correct.

Carbon dioxide

SOURCE:- carbon dioxide can be from both human and natural source. Example of the sources includes; natural source ( ocean release, decomposition and respiration), human activities ( burning of coal, oil and natural gas, cement production etc)

IMPACT:- carbon dioxide causes difficulties in breathing as it displaces oxygen in the air.

Sulphur dioxide

SOURCE:- sulphur dioxide mainly occur due to human activities such as fossil fuel combustion at industrial facilities, in ships etc.

IMPACT:- Sulphur oxide has been linked to many health effect and diseases such as cardiovascular diseases. It also causes respiratory problems, asphlegm and asthma attacks, irritation of lungs, throat and nose as well.

Nitrogen oxides

SOURCES:- nitrogen oxides also comes from human activities such as; combustion of fossil fuel, making of nitric acid, refining metals as well as petrols, explosive, food manufacturing etc.

IMPACT:- Nitrogen oxides has also been linked to many respiratory health issues such as bronchitis and wheezing. It causes the lining of the lungs to inflame there by reduce the immunity of the lungs to respiratory diseases.

Methane

SOURCE:- methane can be from either natural or human activities. The natural source includes; food digestion by cattles, decay of organic materials. Human activities such as waste management, rice production, oil and gas production etc.

IMPACT:- Methane is considered a green house gas like carbon dioxide, it contributes to the trapping of heat energy in the atmosphere which causes global warming. It is also linked to serious health issues such cardiovascular, respiratory and neurological problems.

Particulates

SOURCE:- particulates are fine tiny particles of matter found in the air, it might be in solid or liquid form. Example; dust, smoke, fumes etc. This particles can suspended in the air for an extended periods of time.

IMPACT:- exposure to particulates can cause variety of respiratory health problems such as difficulties in breathing, coughing, lungs and heart problem etc.
