“Currant” is ‘a type of raisin or an edible nut’.
“Current”, a more common word, means ‘a steady, smooth, onward movement’. Thus the first word is “currants”. (The cake had lots of currants...)
“Exceptional” is a positive word, which means, ‘outstanding, excellent’.
“Exceptionable” (the second word) means, ‘objectionable and hence liable to be punished.’
For the third word, both “consent” and “assent” mean ‘to agree’. However, “assent” is more in tune with ‘yielding to something’ or ‘conceding’ whereas “consent” is more about ‘permitting or approving’. Therefore the appropriate word here is “consent” as an adult would “consent” or ‘give permission’.
In the fourth sentence, a minister is not “compelled” (forced) but “obliged” (necessitated or required) to report regularly. While oblige may have a connotation of force as well, compel clearly means ‘forced to’. Therefore, “obliged” is a more appropriate word here.
When we say something is “genuine”, it is not more or less, it is ‘simply and completely authentic’.
Therefore, far too will apply to the adjective “sanguine” which means ‘far too optimistic’ or ‘confident’.
Therefore, the correct sequence is BBAAA.
Hence, the correct answer is option 2.
