True or false threatened species are at the highest risk of extinction

The given statement is true.  

Any species like plants, animals, fungi, and others, which are susceptible to endangerment in the coming time are considered as threatened species. The IUCN treats threatened species not in an isolated category, but in a group of three categories, on the basis of the extent to which they are threatened.  

The threatened species are also considered as a red-listed species as they are named in the IUCN red list of threatened species.  

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
