(10 Points) Government agencies consider the possibilities of earthquakes when they
are developing regulations about new construction projects. Regions of
the United States are classified as having a low likelihood of earthquakes
(lowest hazard), a high likelihood of earthquakes (highest hazard), or
somewhere in between.
Which two statements should inform the development of building
regulations in regard to earthquakes?

i believe the answer is a.

a:

by the combination of an unlimited number of elements

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
