Which statement best describes the use of catalytic converters in automobiles? O They decrease the rate of the reactions that produce harmful gases.
O They oxidize hydrocarbons to form less toxic gases.
O They combine the larger hydrocarbon molecules with smaller ones.
O They increase reaction temperature for cleaner burning.

the answer is a

photosynthesis

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

catya that's not even a b or c
