Sometimes, speakers use the present continuous to indicate that something will happen in the near future, like, travel to Srinagar this weekend. The present continuous is formed using am/is/are + present participle (ing). Hence, Option B is correct. The rest of the options do not contain the correct verb forms. They mention actions that happen on a daily basis (option B) and incomplete verb forms (options C and D, without 'am': 'am going to travel and 'be' in 'would be travelling'). Hence they're incorrect.
