What’s the question and isn’t this a maths question??
Answer:
x) there is less demand at night
Explanation:
Electric power and it's the price is dependant on the level of demand it has, there are peak and off-peak times during the day, generally speaking <em>during the night (between 10 pm and 7 am) electricity has lower demand</em>.
The existence of peak times at a day is the reason why<em> hydroelectric generation is lower at night</em>, normally in peak off times the hydroelectric generator stores water for when the demand increases, same happens with <em>powerplants at night not being as efficient as they are during the day when the energy is more needed.</em> Finally, <em>pollution control is stringent at all times of the day, its not related to the demand.</em>
I hope you find this information useful! good luck!

Balkan Peninsula is a headland of Greece, Bulgaria, Yugoslavia, Romania, Albania and Hungary under Ottoman Turkish rule. It is a geographic area in a southeastern part of Europe. The country takes the name from Serbian-Bulgarian border to the Black Sea’s Balkan Mountains. The geography was rotating around its three characteristics: its mountains, its rivers, and its area’s situation. The Peninsula itself is a triangular shape with a broad northern borderline, straitening to a tip as it extends to the south surrounded by the Black, the Aegean, the Mediterranean and the Adriatic Seas; they served each other as barriers and access points. Balkan is different from other peninsulas, it is not being secluded from nearby regions. Most of the ethnic groups in the region were entering in the access points of Romania in the northeast, Ukraine in the steppe regions, Danube and Hungarian in the northwest. Balkan is surrounded by 3 sides of water; the neighboring regions to the east, west, or south, the narrow channels of Bosphorus and the Dardanellas which are the natural passage between Anatolia and Balkans, and beyond Asia. Balkan is unsurprisingly a region that has been intersections for traffic accessing to and from all these destinations.
