MOPU refers to a Mobile Offshore Production Unit, which is a floating platform used in offshore drilling operations for oil and gas production. It is designed to support production equipment, with no need for a permanent structure.
Step 1: The MOPU is critical for offshore production in remote locations.
Step 2: It is not related to piping, oil, or process systems, which eliminates options (A), (B), and (D).
Thus, the correct option is (C).
Figure shows an inextensible catenary mooring cable in still water. The submerged weight (per meter length), and the anchor radius are 100 kg/m and 50 m, respectively. If horizontal tension ($T_h$) in the catenary is 1600 kg, the catenary length (AB) is ............. m (rounded to two decimal places). 
Identify the option that has the most appropriate sequence such that a coherent paragraph is formed:
Statement:
P. At once, without thinking much, people rushed towards the city in hordes with the sole aim of grabbing as much gold as they could.
Q. However, little did they realize about the impending hardships they would have to face on their way to the city: miles of mud, unfriendly forests, hungry beasts, and inimical local lords—all of which would reduce their chances of getting gold to almost zero.
R. All of them thought that easily they could lay their hands on gold and become wealthy overnight.
S. About a hundred years ago, the news that gold had been discovered in Kolar spread like wildfire and the whole State was in raptures.
