On the footing of this information, yous accept to choose the  alternative which shows that Influenza A virus subtype H5N1 is the granddaddy of T.

2. AxB+C-T
3. A+C-T
4. A+B-CxT
5. A-CxT

Solution : 

Option (1) represents that Influenza A virus subtype H5N1 is the granddaddy of T

• i) B-T --> B is the sis of T.
• ii) S+B --> due south is the manlike individual raise of B, thus due south volition live manlike individual raise of T (from information (i))
• iii) Influenza A virus subtype H5N1 + B --> Influenza A virus subtype H5N1 is the manlike individual raise of S, thus Influenza A virus subtype H5N1 volition live granddaddy of B. 

Ex. vi : If 'P$Q' agency that P is the manlike individual raise of Q. 'P =! Q' agency that P is the woman raise of Q, 'P*Q' agency that P is the sis of Q. Then , how is Q related to northward inwards N=! L $ P * Q ?

In the higher upwards question, the gender activity of Q is non given, thus exact human relationship betwixt northward too Q cannot live established. In other words, nosotros tin tell that information is non adequate to answer the question. Therefore, the right answer is (4).

Ex vii : If 'P+Q' agency that P is the woman raise of Q, 'P %Q' agency that P is the manlike individual raise of Q, 'P-Q' agency P is the sis of Q. Then, which of the next human relationship shows that grand is the miss of R ?

1. R % M + N
2. R + northward % M
3. R - grand % N
4. Data inadequate
5. None of these 

Solution : 

M + northward i.e., grand is the woman raise of N, hence, the gender activity of grand is determined every bit female. R % grand i.e., R is the manlike individual raise of M. Hence, R + grand + northward clearly hateful that grand is the miss of R. Therefore, the right answer is (1) 

That's all for straightaway friends. In my adjacent lesson, i volition part few to a greater extent than blood relations problems amongst higher difficulty level. Happy Reading :)
