Question:medium

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When a flexor muscle is excited, the probability of excitation decreases in the paired extensor muscle.
Reason R: The interneuron that excited a motor neuron to the flexor muscle also inhibited a motor neuron connected to the extensor muscle.
In the light of the above statements, choose the most appropriate answer from the options given below

Show Hint

Reciprocal inhibition is a fundamental spinal reflex mechanism. Inhibitory interneurons are the biological "switches" that turn off the antagonist muscle when the agonist muscle is turned on.

In an oligopolistic market, firm i and firm j have constant marginal cost = c for an identical good. They compete to set prices Pi and Pj. The demand for total market demand Q, where if \(P_i > P_j\), the demand for firm i is 0. If \(P_i < P_j\), the demand for firm i is Q. If \(P_₁ = P_j\), then they share the market equally and hence the demand for firm i is \(\frac{Q}{2}\). In equilibrium, the prices of firms i and j are:

In the table below, firm 1 and firm 2 can cooperate to share market profits or compete with each other. The figures in the cells represent the profits in crores of INR. They can either cooperate with each other where they share INR 10 crores equally. Alternatively, they can compete, which lowers the market output to INR 4 crores, which they share equally. If one of the firms competes while the other cooperates, the former obtains INR 10 crore of profit while the other makes zero profit. In equilibrium, firm A and firm B should respectively:

Firm 2	Cooperate	Compete
Firm 1	5, 5	0, 10
Compete	10,0	2, 2
