Light bends away from the normal, because it's moving from higher to lower refractive index.
Same bend-direction as when it goes from water into air.
For reducing erosion of water banks, "Buffer strips" need to be used
In short, Your Answer would be option A
Hope this helps!

Elaborate rehearsal involves organizing and breaking down information into easier groups to expand capacity. Rehearsal is the verbal repetition of information. These techniques are especially important for the improvement of long-term memory.
Six strategies of elaborate rehearsal are:
1. Rephrase information into your own words.
2. Create your own study questions and answer them.
3. Use images to help you.
4. Group terms that are of the same topic together.
5. Use a mnemonic strategy.
6. Space our your learning and don't try to cram in on sitting.
Answer:
(a) decrease
Explanation:
Viscosity is the resistance which occur to flow of the fluid.
More the inter molecular forces between particles of the liquid, more the viscosity of liquid.
<u>Effect of temperature on viscosity:-</u>
Viscosity decreases with the increase in the temperature as forces among the particles decrease on increasing temperature. The kinetic energy of the particles of the liquid increases causing to move in more random motions and thus weaker inter molecular forces and this offer less resistance to the flow.
<u>Hence, viscosity of the liquids decrease with the increasing temperature.</u>
