'As' suggests a sense of urgency. It suggests that 'she ran up the stairs the moment she saw her father'. 

 Here, one action will happen only if the other happens. In such cases, we use 'if'.

'Even though' means 'despite the fact that'.

Here,'even if' means 'despite the fact that'

'However' means 'no matter how' in the sentence.

'As if' means 'like'. The sentence implies she looked like she had seen a ghost.

 The sentence implies that he should do 'like' his boss wishes.

The auxiliary verb need is followed by an infinitive without to. It doesn’t have forms like needs or needed.

‘The Committee’ is singular. Hence, ‘has’ will be used. No other option makes sense here.

'Will' must be followed by 'be' to make any sense here. ‘Was’ is the correct option because ‘he’ is singular.

‘Spectacles’ is a plural. Hence, ‘have’ will be used. Other options do not make a meaningful sentence here.

'The commission’ is a collective noun and is treated as plural when the members are divided in their opinions.

The auxiliary verb dare is followed by an infinitive without to. The auxiliary dare is common in questions and negative sentences. It doesn’t have forms like dares or dared. Questions and negatives are made without do.  

‘Is’ is used because ‘pair’ is a singular subject. The use of present tense makes more sense in the context of this sentence. So, option 2 is correct.

Option 3 is correct because of language etiquette as per which 3^rd person comes first, 2^nd person after that and 1^st person at the last.
