(1)the concentration of products and reactants is equal
(2) the concentration of the products and reactants are constant
(3) the rate of the foward reaction is less that the rate of the reverse reaction
(4) the rate of the foward reaction is greater that the rate of the reverse reaction
is the answer 2?

Yes, you are right. Concentration remains constant in a reaction at eqilibrium.

The answer is 2, however, consider
If you take away product, the reaction shifts to the right to restore equilibrium so that the Keq, as determined by products x prod divided by reactants x reactants (put in superscripts as appropriate) is restored.
An example: SO2 in water > H2S03 reversible.If SO2 escapes, the concentration of H2SO3 goes down because some dissociates to restore the equilibrium but only enough to maintain Keq. Then concentrations are constant again.

Yes, the answer is 2. When the concentrations of products and reactants are constant, then the net forward reaction and net backward reaction are at equal rates, and the reaction is at equilibrium.

Yup, the answer's 2. 1 doesn't work because equilibrium just means the products and reactants are reacting at an equal rate, which doesn't necessarily mean there's the same AMOUNT of them there. 3 and 4 defy the definition of equilibrium: the rate of the fwd rxn has to be EQUAL to that of the reverse rxn.

Yes, because the rate of the forward and reverse reactiosn are equal

the substances combine and form a new substance.
or the substances retain its original property
