D Correct answer
Explanation

Correct Answer: had been climbing As 'ran' is in past tense we know we need to use the same tense. Out of the options past tense can be found in options 2 and 4. But 'had' is used with either 'past participle form' or 'been + present participle'. This correct usage is found only in 'had been climbing' which is  'past perfect continuous'. So, option 4 is the correct answer.
