| II. | Get your feet wet | Establish yourself securely in an establishment |

Method. idiom 'clarion call'
A clarion was a medieval war trumpet; a clarion call is a strongly worded appeal or summons to action (Oxford Dictionary of English). (a) is only the literal sense; 'strong request' (c) is nearer than 'urgent order' (d) because it is an appeal, not a command.
Loose match: (c) taken as nearest to 'strong appeal to act'; (d) 'urgent order' is the competing option.

'Pull up' means to come to a halt (of a vehicle) and, of a person, to stop or check: 'pull someone/oneself up' = cause to stop or pause, check (Oxford Dictionary of English; Chambers: 'pull oneself up' = check oneself). Of the options, (b) 'to check oneself' is that dictionary sense. (a) and (c) are literal misreadings; (d) as printed ('Too short of destination') states no meaning, and 'stopping short of a destination' is not a sense the dictionaries give.
UPSC's option (d) is printed as it appeared, 'Too short of destination'; the answer rests on the dictionary sense 'check (oneself)'.
