its most likely Table salt

as water has a boiling point of 100 so it can't be 

hydrogen has a very low boiling point below 0 so it can't be

gold has a very high melting point as its a metal and melting point higher that table salt 

hope that helps

Answer : The correct option is, (d) Table salt.

Explanation :

The melting point and boiling point of given substances are :

 Substance          Melting point,\(^oC\)         Boiling point,\(^oC\)

(a) Water                        0                                     100        

(b) Hydrogen                -259                                 -253

(c) Gold                        1064.43                            2807

(d) Table salt                  800                                 1465

From the given substances, table salt is an ionic compound which has high melting and boiling point while others (water and hydrogen) are covalent compounds. And the gold is also has high melting and boiling point but as the value given in the question matches with the table salt.

Therefore, the correct answer is table salt.
